Fuel Pump Problems

Hello Guys,
I'm in need of some help!

A few months back a whining noise was coming from the in-line fuel pump on my '82 1.6 gti. It would also cause the car to cut out. I pressumed that the problem was due to a blockage as i had stupidly left the fuel level get quite low. The fuel pump was replaced and the problem was sorted.

I took my golf out this week and the same problem happening again, although not as severe; I managed to limp the car home. Slight bubling and some fuel appeared from the nut on the fuel pump; the main body nut and second one with the coppper washer inbetween.


I'm wondering whether the nut just needs tightening up or do you think there are other underlying problems? I would simply tighten the nut up and try it but the fuel pump is now off and wanted to know if it's worth investigating anything else while it's off the road now? Is there anything else I should look out for?

Many thanks for any help!

the fuel pump union part is a non-return valve and should be nipped up into the fuel pump housing, usually its nipped up enough once you tighten the end nut

on mine the valve itself failed randomly one day

Sorry to hi jack bud, is that a special none return banjo then Rubjonny cause I've just fitted a normal banjo to my 1.8 gti. 

Was the nut and end of the fuel pump squashed and dissorted  by the copper washer nearest the fuel pump when you fitted the pump as that might be why it leaks as you may not be able to seal the system, it does run at a high pressure.

you need a non-return valve on a kjet car otherwise it will loose pressure when the engine is switched off, whic hwill lead to vapour lock in the fuel lines and hard warm starts on an EFI car its not required though

they are available from classic parts:

the cap nut on the end is N  0110691, and the fuel pipe copper washers are N  0138128. I cant see a washer listed for the NR valve, maybe it comes with one? if not one of the cap ones will probably work

I'm now running a g60 engine so I assume I don't need a none return valve. Thanks for that much appreciated. 

yup its not needed for the g60

It was a new copper washer when we changed it.
Crimped the accumulator to pump fuel line, so now have to replace that aswell. Cheers for the help.
