fuel shortages, i think?

(1/3) > >>

tjsj:
I bought a 1991 2.8td trooper the other day and it is suffering from fuel shortage, I was just wondering where the fuel pump is on these? Does anyone have any ideas on how to solve it?

Drift:
To get at the fuel pump you need to take the timing belt off.

The problem could just be that the filter needs priming or the fuel intake in the tank is blocked, or possible its loosing pressure due to a corroded fuel pipe.

tjsj:
So there is no pump on, in or next to the fuel tank then? The fuel lines do look quite rusty. As the car is only being used offroad, is it worth extending the rubber fuel lines to another tank in the boot? It has got a hand pump thing on it which pumps diesel through, it will run fine if you keep pumping this which leads me to think it could be fuel shortages, I have an old ford escort diesel in the garden. Is it worth taking the fuel pump of that and putting that in the fuel line to see if it pumps any more through?

Drift:
It sounds like there is air in the system, pump the fuel filter untill it gets stiffer  :shock:  that should take any air out of the system.
Also on the bottom of the filter there should be a screw , loosen this and some moisture should come out (water) this could be another cause, its normal for some water to be there. Tighten then repump.

Check fuel tank breathers also s this could cause a vacume in the tank.

All things to check before taking things to bits  :D

Failing that crack an injector to see if fuel is coming through.

tjsj:
well, i have been pumping for ages and still no joy. Is it worth taking out the "in" fuel line and placing it in a bucket of diesel to see if it is actually pulling any fuel through. How do you take an injector out, im hopeless with diesel engines! :?  :?
