    Fast Intentions, Inc. is proud to present our VQ37VHR FAST-500E (ethanol compatible) Return Fuel System. With the birth of our twin turbo kit, we did extensive R&D on the 370Z and OEM fuel system. It did not take long to see that the OEM fuel system could not support forced induction reliably. As the load and PSI (Pounds Per Square Inch) increased, the fuel pressure would decrease. This limited our controllability over the air fuel ratio in the higher rpm’s. The FAST-500E Return Fuel System is an ethanol compatible version of our FAST-500 Return Fuel System. This system utilizes an Aeromotive Sport Compact 1:1 boost reference fuel pressure regulator, Aeromotive 10-microns, microglass fuel filter, our billet CNC aluminum fuel tube adapter block, a dedicated feed line to supply adequate fuel to the fuel injectors and the CJM in tank OEM regulator delete kit. Our #1 goal with this fuel system was to supply adequate and constant fuel pressure at idle and under WOT (Wide Open Throttle.) The tuner now has full controllability over the air fuel ratio throughout the rpm band. This fuel system is a must for all that want to make 500-wheel horsepower and beyond in a safe and reliable environment! – Ethanol Compatible
