Fuel accumulator is bosch 0 438 170 040, VW part number 431133441D or C

0 580 254 909 and 580 464 126 will both work fine for a MK1 GTI :)

I need a new one and the Heriatage one is about £250. 
I can get one of the above for half the price. 

I know it's an old post but fingers crossed.

I bought a genuine Bosch 0438170040 off Amazon last year. Still listing at £135 with free delivery.

I was potentially needing a new accumulator earlier this week - but it turned out not to be the issue. After reading a few threads across various forums, and chatting with someone direct on here, you can use a 0438170039 accumulator, which from what I could see don't have the scene tax applied to them!

My rebuild thread I will try and keep up to date: here

It holds the pressure in the fuel system when you switch the engine off so makes hot starts easier.
There is a little screw on the back and if you remove that and fuel leaks out it's shot.
