Hi everyone,
I'm trying to identify a fuel leak on my 1986 944 Turbo.
It's around injector one.
Fuel starts to appear when you turn on the car, but it seems that it continues (and perhaps even increases) in the few seconds after you turn off the car.
My current thinking is that it is not the injector itself like I first thought, but rather the rail in that area. Reason for this is that I visually identified areas of 'weeping'/'welling' on the rail and not directly on the injector. All injectors have brand new, fresh seals. The injectors sit as they should. All fuel lines are new. Fuel rail is the original one from 1986 as far as I can tell.
Here are some photo's that show the leak(s) location(s):
This is the area that seems to have a sort of 'fuel well', fuel keeps appearing there, slowly:
This is the back of the 'well area' but it also seems to have its own problem. Fuel also appears here it seems:
This is the area where fuel pools:

I've seen two different 951 fuel rails leak at the seams. If it looks like yours is leaking, I'd pull the rail and test it for leaks. On the two I had (not my car), the leaks were pretty easy to find.

My new fuel rail arrived, gonna install it tomorrow!
Edit: I replaced the fuel line and took all other hardware off the leaky one and put it on the new one.
I'm happy to report that I have no more leaks! Great success, that costed me 800 EUR
