i did search for (fuel leak) but couldnt come up with anything related...

anyways 94 gsr i have a leak coming from one of the fuel line fittings onto the fuel filter. i dont have my car here at work but i think there are only two places that can be tightened/loosened on the fuel filter.

the line going from filter to rail is tight as can be, but the bigger fitting, directly on top of the filter, may be loose. i havent had time to check it yet but has anyone ever had problems with this before?

it has a Walbro fuel pump with AEM fuel rail running on a P05 ecu. ( i know its the wrong ecu, i have a p28 im swapping in today, will be chipped in a couple of weeks).

the guy who owned the car before me had a P06 ecu in it and when i test drove it, there wasnt any fuel leaks so im assuming its having to do with the fuel pressure ratio from the p05 and p06, maybe there is a differece? im hoping the p28 will solve that, IF that is the problem.

thanks

 

1.ECU's do not control fuel pressure, the fuel pressure regulator does.
2. What exactly are you talking about. Is it #12 or #4 thats leaking?

 

there is a "crush"washer on the top of the bolt and the bottom get a new fuel filter and new crush washers they usually come with the fuel filter.............

 

its number 4, that connects directly to the top of the fuel filter. but where is the line that goes from rail to filter? because that one is kind of wet also.

 

#4 is the rubber line that goes from the filter to the fuel rail. The fuel rail is not shown in that diagram.
