As usual thanks for the sound advice diamond.   :smiley:

I think the filter arrows pointed back to the tank so i assume it was on the return line.

Its very hard to see but behind the filter on the next sill is a bent aluminum plate in the shape of an L which i am guessing used to hold the pump prior to the cowboys installation.

Do accumulators need replacing over time? as mine looks rusty from the outside and i know has been sat for years.

If anyone has the ETKA diagram for the original Audi fuel pump that i have installed i would be forever indebted.

Sorry for so many questions guys, I have done a some DIY mechanics but this scares me a bit as its not T25 or K-Jet specific, and as i dont know who installed it I'm pretty much on my own :(

filter and accumalator are seperate units.   VAG fuel injection filters  are large metal canisters.  also very inportantly the filter goes after the pump on the pressure side. 

reason been is the high pressure pumps cannot suck very well and restriction to fuel feed will cause problems the filter is there to protect the injectors and metering head, the pump can deal with crud when there getting old they more than likely create crud.

it's not massivy urgent but i would get that crappy plstic filter from there   it's not big enough and there brittel  one good wack and it may breack
all the VW's have gone bar 1.

yep as above, the pump looks like a MK1 GTI tintop setup, and I can see the accumulator is there too. Just need to fit a filter along the line somewhere, MK1s have these in the engine bay on a bracket in front the front of the fuel metering head, this would probably be eaisest for you?

Accumulators do fail over time, generally all that happens is it makes the engine hard to warm start, as fuel pressure is lost and the fuel in the lines evapourate due to engine heat.

In addition if you do suffer from fuel starvation get a fuel reservoir from a late MK1 Cabby/scirocco, or a MK3 polo. this will give you a fair bit of fuel reserve.
