Apply a small amount of White Lithium grease to the O-rings and reinstall.

While most of the fuel will drain out pass the piston rings, a severely leaking injector can cause hydro lock.

If your car is starting to run rough, getting horrible gas mileage or has an error code, there is a good chance it is time to replace the fuel injectors
Modern fuel injectors are made of plastic and we do not recommend having them serviced or rebuilt. Older mechanical injectors opened by fuel pressure alone and were easier to service; newer injectors are made of plastic, need an electronic pulse from the ECU to open and are better replaced than sending them out for service.

mk3 golf stuff might do you better, can use a mk3 gti/16v/vr6 pump and do away with the under car pump. can get tank, lines, filter carrier from any petrol mk3.

but if i was going to run a k-jet pump (and planned it in advance) i would remove all the lines and the accumulator from the k-jet pump and buy a barbed fitting off ebay to convert the pump to take standard push fit fuel lines. fit a mk2 digifant fuel filter and lines! the k-jet lines are metal and like to rot, plus can be hard to find.

Are the Golf mk2, mk3 and Corrado tanks the same in terms of interchangeable between vehicles? Filler necks in the same place etc.

I'm interested in this too - I've bought the MK3 tank and pump but want to plumb it to the K-jet set up and wondering how?
