Alistair,

What do you mean when you say the pumps ‘click’? Mine (on an 85 XJ6)
have a constant whirring sound (similar to the electric aerial motor but
not as loud) even if the engine has not started. Do I have a similar
problem to yours - it just manifests itself in different ways because of
the different vintages associated with the pumps?

Cheers,

Subject: Majordomo

Aaargh! Sending a “who jag-lovers” command to the majordomo results in a
list of only the members’ e-mail addresses – no names, what cars they own,
etc. Seems a poor substitute for the list we had been getting from Scott.

Opinions? Is the majordomo output adequate, or do we need to do
something? If so, what? Can we keep a list of members on the FTP site?

If we do decide on an FTP site list, I would like to see it even MORE
involved than Scott’s list was. Perhaps a little background. Might even
ask each member to post their own intro for inclusion.

Well, today I had another crack at my faulty fuel supply again.
Regular readers with good memory may recall my mentioning this

What I have determined that both pumps get their rightful
electricity and I have emptied and hosed out the suspected
^^^^^^^^^^^
Well, how about some basic electricity 101 today? How did you measure the
electricity ??? With a volt meter and you saw 12 volts across the leads???
This is a good basic first test, it tells you if you have a broken wire.
But it doesn’t tell you if the circuit has high resistance (like a
bad/corroded connector) which limits the current (amp) flow through the load
(fuel pump). Suggest you do this voltage measurement again with a load
across the fuel pump wires. How much load??? I don’t know, how many amps
does the fuel pump require/draw??? I’ll take a guess, put a 10 ohm, 10
watt, resistor across the wires, this then will draw around 1 amp. Then do
you still see 12 volts across this resistor? (It will get very hot, be
careful). If yes, then I’d bet on a bad pump. If no, then you have a
circuit/wiring problem.

BTW, skipping electricity 101, another perhaps simpler check would be to
hook the wires from the good fuel pump to the suspect one. Now does it
work?

Kirby, I have been meaning to write something with regards to
this for a couple of weeks now. The Majordomo output is much
less satisfactory than the survey Scott put together.

I was going to suggest a member-list on the web-site, with the
possibility of people having a picture of themself and their
car(s) if they wanted to. If people mail me photos I am only
happy to scan them.

The problem with this is that there are relatively few members
that are as involved as the “hard-core”. Seeing how few regular
posters there are it is hard to imagine that the list is well
over 200 strong at the moment… By all means ask people to
post a few words about themselves, I’ll be surprised if more
than 25 reply. I’ll be full of joy if I am proven wrong tho :slight_smile:

No. Tried it, the good pump still works and the “bad” pump

some info for North American tilting comapanies:

Accessable Systems, Inc.
440 Matson Rd
Jonesborough, TN 37659
(615) 928-3996

They offer a product called “The Bottoms Up” lift (a big jig that looks like
you can rotate the car 360 degrees, in both stationary and movable models)
and the “MPS Auto Cradle”- which is hard to make out in the picture.

Liqui Technics
119 East Quail Trail
Covey Creek
Lewes, DE 19958
(302) 645-4819 or FAX (302) 645-4819

They make the “Liqui Vehicle Tilter”. From the ad
“Any auto/van/small-truck up to 6800 lbs can be tilted at an angle up to 90o”
“Tilter weighs only 136 lbs”
Apparently, you use a drill to lift the vehicle with this one.

Both of the above show complete cars mounted on the jigs.

I’m sure either company would be “happy” to send you their

Thought I’d jump in and try and help here. The clicking pumps are SU non
fuel injected ones. They are suppossed to click when running, the noise is
the contact breakers (beneath the black circular cap. The whirring pumps are
much higher pressure to serve the FI.

The “clickers” often suffer from sticking points, these can be cleaned and
rest like distributor points.

I have been told that some European models of the XJ6 had 7" headlights in
the outside set. So far I have been unable to confirm this.

If it is so, I would like to aquire drawings of the way they were mounted at
the least. I would realy like to find a set of hardware that I could
purchase at a reasonable price. I want to mount a pair of 7" halogen

If anyone has pictures from an owners manual, or something simular I could

OFFICE MEMO Transistorized SU Fuel Pump Date:3/29/95

Hey, just in time for Alastair and Nick, I was putting together a report on
how I rebuilt my Mark V fuel pump with a modification.

First, for Dave, your injected car has a different kind of pump from the
carburetted cars. SU pumps on carburetted cars have an electromagnet, a
diaphragm and a set of points. The steel disc on the diapragm is what clicks.
Yours is an electric motor which I think should whirr only when the engine
is either cranking or running. If the engine is shut off or if after cranking
it fails to start, and the pump keeps whirring, I believe that would indicate
a problem in the pump relay or the air flow sensor.

I just finished rebuilding the original pump for my '50 Mark V last week, and
this time I added a transistor and a diode according to a scheme published by
the Classic Jaguar Association in July '89 and Jan '90. They got it from the
Vintage MG folks. Most of your SU pumps will have a capacitor which sorta
protects the points for awhile but eventually they burn out. My MkV didn’t
even have a capacitor, so the points really arced something fierce.
Apparently the MG mod lets the transistor do the coil switching work, so the
points last indefinitely, no more tapping the pump with a hammer or slamming
the car door to get it going again.

From Radio Shack or another electronics supplier you need:
one transistor…for negative ground get a TIP 32 PNP
…for positive ground get a TIP 31 NPN
one diode…200V 1A microminiature type 1N4003…same for either ground
(or an alternative diode 1N4002 can be used)

Get these parts from one of the aftermarket Jag parts suppliers.
One contact points set and one diaphragm for a single pump, or two for a
double pumper.
You might need: one-way valve discs (some are plastic, and they do break)
Notes: get the double contact type points, not the single. There are two
lengths for the diaphragm stem, Mark V is the longer one, I think XJ6 should
be the shorter one.

Procedure: Remove six screws around diaphragm and gently peel it off the
aluminum body. This contact face is a sealing surface, so don’t gouge it with
a screwdriver like I did my first time. Clean the crud out of the body and
check your one way valves (a gozzinta and a gozzoutta). You can push up on
the diaphragm to see the toggling action of the points. Note how much the
stem is screwed into the center pivot of the points, and try to duplicate
with the new diaphragm, but you don’t have to be super accurate about that.
The diaphragm has either a plastic centering spider or 11 centering brass
discs to center it in the cast iron coil body. Unscrew diaphragm from old
points, replace points and screw in new diaphragm. Push on the diaphragm to
check toggling action of the points and bend the tab to adjust the travel of
the moving points (I found a couple of new sets of points didn’t flip over
right, had to bend the coil spring a bit). Bend and/or adjust the stationary
points to get a good contact with the moving points. Good contact and good
separation is what you’re after. Put in centering spider or discs, put fuel
sealant on contact faces, and tighten down six screws diagonally and
uniformly. Note the small drainhole in the coil body is supposed to point
downwards. Bench test it with jumper leads from your battery, it should
rattle away at about 3 or 4 cycles per second. Installed, it should fill up
the carb bowls and then slow down to like one click every two to ten seconds.
At this point your pump is just as good as it ever was…

Now for the mod:

From this moment it becomes either a positive or negative ground only pump,
so decide which you want.
First disconnect the one coil wire from the blade contact point small fixing
screw, and remove the capacitor. The other coil wire is your 12V input, and
stays as is.
The transistor has a mounting tab which I drilled out to fit on one of the
two existing large mounting screws for the bakelite bridge. Use either one
you like, since you won’t be reinstalling the capacitor.
Note the transistor has an emitter, a base, and a collector. Regardless of
whether you are doing a PNP for negative ground or an NPN for positive
ground, the connections are the same.
The collector is grounded to the coil body, as is the wire from the flipover
contact points.
The base terminal is soldered to a wire which connects to the small screw
which holds the blade contacts.
The emitter is soldered to the coil wire that was removed from the small
screw above.
Now for the diode: For both positive and negative ground the diode is
soldered between the emitter-to-coil joint and ground, but in opposite
directions. The forward direction was shown on the package I bought, looks
like an arrow running into a wall.
For negative ground (earth): the diode forward direction is from ground to
the emitter.
For positive ground: the diode forward direction is from the emitter to
ground.

The result is a pump that rattles away with not a bit of visible arcing and
sparking at the points.

Piece of cake, right?

Subject: RE: Petrol Pump Clicking “Patterns”

An inquiry was made about fuel pump clicking patterns on a non-FI car. Fuel
pump “clicking” on E-Type coupes and 2+2’s is quite noticeable, as they are
in the back of the load area, just a few feet from the front seats – e.g.,
right there with you.

My experience has been that they (referring to my coupe and my friend’s 2+2)
typically click for 5 to 10 seconds or so when first turning the key to on,
and click at a rate that is inversely proportional to engine speed/load –
e.g., if the engine is using a lot of fuel, the pump needs to cycle on and
off less frequently.

I have, twice in the last two years or so, had the pump click like mad on a
hot day (I assume from something along the lines of vapor lock or something
of that ilk), but the clicking rate is generally more like once or twice per
second for the afore-mentioned startup period.

When you switched suppy to that tank, there never seemed to be enough fuel

and the fuel tank was sucked in by the pump, partly collapsing it! You could
never fill that tank and it had to be replaced.

I’m wondering what is the symptom that you experience when you have
fuel problems (e.g. bad fuel pump, clogged fuel line). Does the car
sputter and die, or just dies immediately? How do you tell that the problem
is the fuel system and not the ignition? What happens after you re-start
the car?

I once asked why parts manuals and service manuals from Porsche weren’t

“that wouldn’t work”… as far as an index what are we talking about? Part
No. to part
name to page number?

The reason that most parts books are on microfiche instead of magnetic media
storage is that the alternate storage schemes for this sort of thing were well
under way in the early '70s, when floppies were 8" diameter and very expensive,
and personal/small business use of computers was nonexistent.

Fiche replace parts books because of cost. To reduce the book to fiche, you
rip it up and take pictures of the individual pages, low cost, medium tech. To
go straight to electronic media would require someone manually type the data
into the computer, and do without the drawings.

Additionally, 48x fiche cards provide higher information density storage than
electronic media, and the end user can access it with a reader/printer, less
expensive than a computer, and very low tech and repairable.

The next step along in this was to have been ultra-fiche, 200x microfiche,
which were at least feasible to produce, though rather a neat trick, but it all
came apart on the simple fact that there was never even proposed an economical
reader-printer for ultra fiche. I once had an entire King James bible on
ultra-fiche, the whole thing was the size of one common postage stamp. Problem
was, you needed a transmission microscope to read it, and forget printing it.

Fantasic stuff!!! My 1974 XJ12L died on the way home on 27/3. I’d had
trouble with my left hand pump refusing it work since Xmas. Due to its
age (orginal) I thought I’d get around to replacing it next service in
May. Well, as I said, I was driving home and the car just stalled while
travelling fast down the freeway. I was using the right hand pump.

Anyway, I’II change the fuel filter, clean out both tanks, flush the
pipes and buy a reconditioned pump this Saturday. My question is:
how much pressure should the petrol pump squirt petrol out passed the
return valve? I removed the pipe returning the petrol back to the tank
from the engine bay, and turned on the pump. nothing much came out.
I could easly hold my finger over the pipe and contain the fuel. I have
the feeling that both pumps are full of shit?
