[modern] XJ6 No Start / Faeries in Petrol Tank?

Recently had a vacation for a few weeks and to my dismay my 2.9 won’t
start. It did previously and I was working on it but now I have to get
it going again. One thing that is strange is that there was not that
much juice in it but now it says that there is more than there should
be. Is there a possibility that water has got in the tank thus making
the gauge go up?? I guess the fuel cap inset to the body could harbour a
nice little amount of water, that may gradually trickle in? We have had
loads and loads of rain recently in UK. I guess there is a chance that
the existing fuel is a bit stale but I don’t really want to put more
fuel in the car if water is in the tank? Can anyone offer some advice -
or if the tank needs draining then tell me how?

Changed brakes on other 2.9 and it took only one hour to do the lot -
very surprised how easy it was!

Hi Darren,
If the car has a tank in each rear fender, they each have a brass drain plug
underneath.Easy to get at and to drain.

Darren,
Its been reported that the tank can fill with water is the drain
in the fuel fill is plugged up.

You could also have water into the ECU,s in the dash if the drains
are clogged.

To get the water out, you would have to drain the tank.
You can pull the line off the fuel pump, and let it drain it out, or
disconnect the fuel return at the front of the rail, and put a hose
on the fuel regulator into a jug and crank the engine till the gas
starts to come out, instead of water.
Crank it 5 seconds on, 15 seconds off…once the gas gets there, the
engine will run…

Moisture in the fuel system can be very bad if it sits in there…the
tank and rail can rust causing problems forever…

Brett,

Based on my experience, I would state this in stronger terms. If the
drain hole in the cup surrounding the fuel filler cap becomes clogged,
and water is allowed to stand above the level of the fuel cap threads,
it WILL introduce water into the tank. Eventually the level of water in
the tank will rise to the critical level and internal combustion will
cease.

For a while at the shop, we were seeing 1-2 tow-ins a week due to this
problem.

Moral of the story: check that the little drain hole is clear each time
you put gas in the car.
