Add a Fuel Bulkhead Fitting (Sold Separately): A major issue with any aftermarket fuel system is a pressurised overflow from the surge tank back to the OEM fuel tank. A common mistake is the use of adapters; the OEM return in ALL instances is far too small and MUST be modified to ensure the fuel flows freely from the surge tank back into the OEM fuel pump module. We've now developed a super flow profile -8AN fuel bulkhead fitting to address any potential issues part number BULKHEAD8AN. Simply cut a small 20mm hole in the OEM module and secure the bulkhead fitting.
Need a Fuel Pressure Regulator? We've made the decision easy and added the most suitable fuel pressure regulator based on the fuel pump selection. We recommend Turbosmart FPR 1200 (1200HP) Fuel Pressure Regulator -6AN part number TS-0401-1104 or FPR 2000 (2000HP) Fuel Pressure Regulator -8 AN part number TS-0401-1106 (sold separately).
Need a Stainless Steel Fuel Filter (Walbro Only)? Aftermarket Industries developed the first and only 200 micron Walbro fuel pump fuel filter / strainer part number W460-SS (sold separately) designed for motorsport conditions and bio-fuels such as ethanol (e85).
Need the Correct Electrical Connector? High current draw fuel pumps such as the Walbro 460, and Walbro 520 require a high performance external e85 electrical connector. We've developed our own as the OEM Delphi Apex 2.8mm 6 way connector are NOT e85 compatible - two (2) connectors are required and ARE included FREE (includes 6x pins per connector and is designed SPECIFICALLYfor 10 AWG (30A) Tefzel Mil-Spec 22759/34 wire
