C5 Return fuel system infomation
It has been brought to our attention that people converting their C5's to a FM FPR have been leaving out a few parts which are key to the proper operation of the system.
One key component that some people have been leaving out is the RR fuel feed hose with checkvalve. Seeing as a C5 does not have a checkvalve in the stem of the fuel pump it is imperative that this line is used in order to keep pressure in the system for startup purposes. Without this checkvalve the system pressure will bleed back to the tank when the car / pump is shut off. This can cause hard start / longer crank to run times.
