Fuel pumps, easy question to someone who knows

[M°°K]

My fuel pump has died and I've been looking about for a used one. I,ve come across a MK2 GOLF GTI DIGIFANT FUEL PUMP, which looks slightly different to the one I need. Mine, straight off the car, has the main plastic box and two round cilinder thingys. The one on ebay only has 1 cilinder thingy. Whats the difference, apart from the obvious.

Thanks in advance

When you have found what pump you need, I have the whole set-up on an 89 digi I am breaking. Will be cheap too!   Spamtastic thread hi-jacking goodness!

I need one that looks like this

Its from a D reg (86) golf mk2 gti.
Any good?
Thanks

i expect thats from a k-jet gti engine, rather than the later digifant engine...

thats a k jet pump,    you need a k jet pump  digifant one won't work.     k jet pump will work with digifant tho

Ah, ok. Thanks for that. Looked on ebay and nothing yet.

I would be carefull buying s/h, any crap / water left in the pump will soon ruin you injection system.
