2.4 JTD fuel leak.

[Dougal]

Had the car serviced a couple of months ago, when we got it home it was parked slightly nose down with a full tank of fuel. When I next took it off the the driveway it had left a large patch of diesel. Called the garage and explained the problem, took it back to them and they couldn't find anything, nor could I.

From then on no more fuel came out, I thought that some had spilled from the filter when it was changed and collected in the sump tray.

Have filled up with fuel several times since and no probs, filled up the other day and it's now doing it again, I may not have parked the car nose down the other times.

Nothing leaks out when the engine is running, it would appear that it must be something to do with a full tank, and maybe the fuel level being higher at the back than the front.

Any body got any ideas, I'm stumped, fuel return cyphoning maybe?

Right, I've found where the leak is coming from, it's the pump, The fuel is leaking from the join in a cover on the side of the pump, only when the engine is turning over just before starting, hence why it was hard to find.

Any body ever experienced this? It's only a very tiny amount.

Unfortunately it is almost imposible to get to the bolts to nip them up a bit.

Bosch, German, Italian parts on the car would appear to be OK.
