CJM S1 VQ35HR Fuel Return System with Pressure Gauge


The S1 VQ35HR fuel system builds on the S0 system by introducing our billet aluminum fuel rails and additional engine bay plumbing. Starting with a 6AN QD adapter for the fuel feed pipe, a 6AN hose feeds fuel into the rear of the RH fuel rail. The rails are joined in the front with a short 6AN crossover hose and fuel leaves the rear of the LH rail leading to the adjustable regulator. From this point back, it matches the S0 system with a 6AN return line leading back to the fuel tank and a return correction kit for the fuel pump housing.
