fuel lines: primary and secondary lines what if they are hooked up backwards?
 

Like the title says, what would happen?

Thanks

engine probubly will not start.

Definitely wouldn't start. No fuel would reach the injectors.

The lines were hooked up backwards ... (I think). The car came that way. where the line coming off fuel filter went to the secondary rail on the LIM, and the one originated from the fire wall superior to the filtered line went to the rail on the engine. It was running and didn't seem to be the cause of my issue regarding tuning and Rtek stumble...

I just switched them back in the engine bay, hoping the two lines were not switched on the tank side by the Walboro 255... it this even possible?

Please feel free to share your thoughts.

Thanks a ton!!!!

Thanks guys,

I did a search and may found the solution. My motor and fuel rail are Jspec, which is said to be "backwards" as the Aspec configuration.

Correct, J-spec engines have the FPR and PD is opposite locations to US-spec motors. The FPR must always be the last part of the fuel system before the return line to the tank. The FPR acts like a check valve if you try to push fuel backwards though it, preventing any flow.
