Our ACCEL inline pump mounts adjacent to the fuel filter, and includes mounting bracket, plumbing components, and relay/wiring for full 12V operation.
Question: Will rewiring the system to bring a full 12V to the intank (Walbro) pump help? Most certainly, but the pump is still straining to maintain that high pressure even with ample voltage. The best advice I can give for the intank pump guys is to monitor fuel pressure regularly to be immediately aware of any deficiencies under high boost. Consider a permanently mounted gauge. HRC owners need not be as concerned, although occasionally using the gauge we provide with the kit is a good idea, especially if you run at 9 or 10 PSI boost. Inexpensive AirFuel meters, although not real accurate in the desired WOT mixture range of about 12:1, can also be a good indicator if a problem should arise.
Nemezis: The fuel system you have is correct, and not in need of updating. Adding a Walbro intank pump should not be neccesary. Should you have trouble achieving full pressure under boost when you run the car again, please contact our Tech Support line (630-801-9065). We will review your setup and recommend diagnostic procedures to find and correct any problem you may have.
