Location of fuel accumulator on late Gti cabriolet

Hi all

Does anybody have a decent image of where the smaller accumulator sits on a late cabriolet Gti please

I have purchased new Bosch one and fuel pump to replace for piece of mind but i cannot for the life of me see where it lives!! 

Id like to have an idea before i take anything apart 

As at the moment i cant even work out if there is one still on the car! It may well have been removed hence me not being able to find it! 

Any help or images much appreciated 

From memory, on mine, 1986 and 1989, 1.8L fuel injected engines, both fuel accumulators sat behind the fuel tank not far from the fuel pumps. Basically between the back edge of the tank and the underside of the back edge or L of the rear seats. Will try to get you some photos tomorrow.

Do you mean fuel accumulator or fuel swirl pot? The swirl pot sat on the side of the tank. Might have photos of that too will check.

Thanks Shubbs 

Just the accumulator location, is it hidden above the fuel pump and carrier in that void or next to it? I can see the white plastic filter type thing is that part of the swirl pot? 

I have a strange feeling that my accumulator may have been removed at some point? As there is a little bracket and what looks like an indent where it looks like something once was! 

Any help or pics much appreciated

yeah the plastic white thing is a fuel swirl pot, assumed to remove bubbles in the fuel line. The accumulator is the bosch thing. There is like an indentation in your fuel tank to make room for the accumualtor. you can see it in the second photo. See photos of location. Dirty photo is the car i havent done yet. the clean one is the car i am currently working on. Not sure i need the accumualtor i am removing the fuel injection and going to run this one on webber carbs. But it shows where its mounted and the mounting arrangement.   

Ah thats superb, thanks Shubbs

And it confirms mine has been deleted! As all i have is the bracket present!

Not sure how they have done it just yet! But im guessing i need to obtain 1 new pipe at least to reinstate it and get the bracket that holds it! 

Many Thanks for your help mate 

A great old school video on the Bosch Kjet fuel system, about 3 mins in explains what the accumulator does.

I guess yours stopped working/sprung a leak at some point and instead of replacing it as they are expensive someone just took it out as the car will still run without it but it makes it hard to start when the engine is hot…


Classic VW maybe able to help with the hoses etc you need.

Cheers, Yeah im guessing that's what's happened, a lot  of these parts weren't even available 10 years ago and expensive so i guess they must have deleted it to keep it on the road

Strangely my car starts fine hot or cold, although it does sometimes just cut out randomly, it can sit there ages ticking over then stops, don't think the fuel pressure is being maintained properly and the accumulator may be why? Gonna replace it anyway

I have worked out i need, fuel pump to accumulator hose with the banjo one end, and accumulator to main supply, the nut that goes onto the end of the pump

Only thing im not sure is if the threaded fittings will still even be there for the hose to thread onto the main feed side to the front of the car? Im guessing maybe not if they put the hose straight onto the pump, which will cause an issue!

I also need to find the small type clamp that holds the accumulator if anyone has one they will part with

ignore the red circle. the rest might help you identify what parts you might be missing. 

Cheers, you i am needing the clamp, the pump to acc line with the banjo end and the acc to main feed line, and some copper washers and the  end nut for the pump

Had a look and i can get all but the clamp online brand new for less than £100 so not too bad 

And i have the added bonus i wont be fighting with old fuel fittings anytime soon 😂
