Car People, Look In. I Have A Great Little Problem

[Will Arnold]

right, heres the scenario: i have a peugeot 205 xld (diesel) 1991. its cutting out constantly.

i have deducted that air it being sucked INTO the fuel lines somewhere. there is a clear pipe between the fuel filter and the the injectoin pump of the engine. once i have bled the system fully and run the engine, it all seems good, there is no air in this pipe, all fuel . but then after a while i start seeing air in the line, then the engine starts to cut out and then stalls - fuel starvation.

my question is, how do you think air is getting into the fuel system?

anyone had any similar problems?

thanks

Will

Air leak into fuel lines is a common problem on all diesel cars.

The air alone will cause cutting out ect, exactly what you are getting.

Unfortunatly the only way to cure is to systematicly test all the fuel lines and elimiate each one.

The best method, get a jerry can full of diesel fuel, and run a pipe from it to each section of fuel pipe on the car, run the car and see if air is in the system.

Work your way along the car, and when you find there is no air in the system, you have found the suspect pipe or connection.

something like that

just saw the picture..

surely i will only have to test the 'feed' pipe, not the return pipe?

9 tims out of 10 its the fuel supply that induces air into the system and causes problems.

But it has been know for certain fuels systems to get air leaks on the return side and have it affect the supply. Usually any air leaks on the return side puts air into the tank, whicj is expelled by the breather.

If you check the supply and dont find anything, check the return, some systems return fuel to the supply side which would give air to the pump.

You might find that the return only goes to the filter and back to the pump rather that back to the tank, it all depends on the manufacturer of the fuel system.
