*PUMPS ARE NOT INCLUDED IN THIS PACKAGE: If you wish to add a fuel pump to your order please add the pump type and the quantity you require to your order from the AVAILABLE OPTIONS above - "Walbro Fuel Pump".

Walbro 460 (F90000274) Fuel Pump

Need a Stainless Steel Fuel Filter? Aftermarket Industries developed the first and only 200  micron fuel filter / strainer designed for motorsport conditions and bio-fuels such as ethanol (e85): see AVAILABLE OPTIONS above - "Stainless Steel Walbro Fuel Filter" (select the desired quantity)

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.

Fuel Bulkhead Fitting (Low Profile 90 Degree)

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 to the AVAILABLE OPTIONS above "Fuel Pressure Regulator"

Turbosmart Regulator FPR2000

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

Aftermarket Industries is not liable for personal injury, death or for any damaged whatsoever arising from any accident or incident where these conditions are not satisfied.

*These tanks MUST not be pressurised, If you plan to use a high volume in-tank fuel pump you MUST use a-8AN fitting as the Overflow fitting located at the top of the surge tank. This will allow the fuel to return back to your fuel tank or fuel cell at the same rate fuel is supplied into the surge tank. Some vehicles may require modification of the OEM fuel pump assembly: If you are unsure, please complete the contact form and we will respond to your questions.
