Need a Stainless Steel Fuel Filter? Aftermarket Industries developed the first and only 200 micron fuel filter / strainer part number W460-SS (sold separately) designed for motorsport conditions and bio-fuels such as ethanol (e85).
Add a Fuel Bulkhead Fitting: 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. Simply cut a small 20mm hole in the OEM module and secure the bulkhead fitting.
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 SPECIFICALLY for 10 AWG (30A) Tefzel Mil-Spec 22759/34 wire
Power Distribution Kit (sold separately)
- Aftermarket Industries now offers a motorsport-grade Power Distribution Kit for up to 3 pumps.
- Dual Pump Dual Relay Power Distribution Kit Part Number LTL-PDM-2
- Triple Pump Triple Relay Power Distribution Kit Part Number LTL-PDM-3
Do I Need to Stage My Fuel Pumps? YES! Fuel pump operation MUST be staged via a Hobbs Pressure Switch, Aftermarket ECU or PDM (sold separately).
Specifications:
- 4 PSI Hobbs Switch
- 24" inch harness with 2x female Delphi 280 Series Connectors & 1x male Delphi 280 Series Connector (includes pins)
Package includes the following items: Requires Assembly (estimated assembly time 30 minutes;assembly guide provided)
