(1999-2013) GM / GMC 1500 & 2500 Return Fuel System Upgrade

The first major step in upgrading your factory-style (Returnless) fuel system, is to convert to a return-style system. A returnless system can not regulate fuel properly with upgraded/multiple fuel pumps. 

This kit gives you everything you will need to add a pressure regulator after your fuel rails, and return unused fuel back to your gas tank. Our Billet fuel pressure regulator is a 1:1 ratio, making it ideal for boosted applications. 

This is the same system we run and designed on our twin turbo shop truck. It has provided us with flawless results over years of use. It has continuously supplied our 700+hp truck with a steady flow of e-85. This way you can directly connect your upgraded fuel pump or On 3 Performance Dual Pump Upgrade Hanger to the fuel hat.

Your kit will include:

• Return Fuel Line (e-85 safe)
• Fittings for Fuel Line
• Custom Machined Billet Regulator Adapter for Stock Rails
• On 3 Performance 1:1 Boost Reference Fuel Pressure Regulator
