[E-Type] Fuel Pump Points

E-Type
1

Brand new Su fuel pump has been sitting on shelf for a few years; Taking
Valerie’s advice, attached power and ground while it is on bench… doesn’t
work unless I put pressure on the points so that they come into contact more
forcefully. Not practical to drive this way as my arms are not long enough.

Is there an adjustment to remedy this?

Any help appreciated.

Yeah,clean the points with a contact cleaner, then take the bottom part
off…screw the diaphragm in 'til the points just don’t break. Back it
off to the nearest hole. Then back it off four more holes. Put it back
together.

Hook it up and test it…

Thanks Jeb - I cleaned the points with emery cloth and then removed the thin
piece of metal holding the outer 2 points, bent it slightly so that when I
put it back the points made better contact…hooked it up and it now works
fine. Wasn’t sure where the diaphragm was. What is contact cleaner? A
chemical available at auto parts store? Is it unusual for a brand new pump to
have points that need cleaning?

Thanks again for your help.

Its sandwiched between the coil and the pump body where the six screws hold
it together…

Most auto parts stores carry some kind of contact cleaner.

It’s not unusual to have to clean points on a new pump. I always bench test
a fuel pump before I install it…sometimes I have to clean the points.

Here is what I hope will be my final word on the fuel pump thread for along
time, Today I took the Bolide out for a ride to see how it would go after
getting the power lead reconnected to the fuel pump on Wednesday. It started
up great, and I ran several errands which involved turning the engine off and
on, and everything was just fine. I dropped my wife off at the Mall to do
some shopping while I ran over to Moss Motors to return something. On the
way there I had one brief moment in which I thought maybe I was going to
experience fuel starvation, but it passed quickly. After Moss I went over to
Driving Impressions to check out racing shoes and pedal replacements. Car
was still fine. On the way home, however, the Prince of Darkness had his
little fun. I was forced to pull over to the side of the road when I
realized that fuel was no longer being pumped! Thankfully, Tom Giffen had
suggested that in an emergency a few whacks with the knockoff hammer would
often jostle the points back into operation. It worked, and I was back on
the road. Happened twice in about a 12 mile trip. [Bummer : ^( ] Returned
home and swapped the E-Type for the XJ6 before picking my wife up at the Mall

    • it would never do to have her in the car with me if I should have the
      need to stop and try to get the pump going again! I’m going to get one of
      the SU solid state pumps from Moss and hopefully install it over the
      Thanksgiving weekend. That should give me a great deal to be thankful for,
      and eliminate what seems like it could become an ongoing PIA! (FWIW, it
      seems like the pump gives out when the demand for fuel is decreased, such as
      when lifting off after a run, or when coming to a stop at a light, or just
      sitting still idling as I was doing at Englishtown last weekend.)

I’m no expert, but I do not think their is any way to
adjust the length of your arms. A rack? Other listers?

All this makes me wonder about others who have said they tap their fuel pump
while driving. Two things: “Tap” as opposed to whack? And how do they reach
it from the driver’s seat to tap or whack it? Is the pump closer to the
front in an O2S than in a FHC?

l. Tap
2. Pump in 65 OTS is located in “trunk.” Like you, gotta stop and get out to
tap.

Sandy,

I guess what I did could be construed as a tap, except when I first read of
guys tapping their fuel pumps I envisioned the use of a finger. Of course,
when I tried that there was no result. So when I found that it involved the
use of the knockoff hammer in my mind it immediately translated into a WHACK!
(Once I had done it I couldn’t get the Lizzie Borden jingle out of my head,
and kept trying to find a way to rewrite it for aJaguar fuel pump!)

Regards,
Warren
