Replacement High Performance Fuel Pump & Install Kit For Walbro 450LPH E85 🇺🇸

Our MadDogPerformance 450LPH pump is the highest flowing intank fuel pump on the market, and is E85 safe to boot. We designed the pump to meet the requirements of modern turbocharged applications where a single 255LPH fuel pump is insufficient. The pump uses a turbine style design which incorporates two composite plastic blades. The turbine design lends itself to extremely quiet operation.

The 450LPH pump can flow anywhere from 15-120psi. Final fuel pressure is determined by your fuel pressure regulator. Please note that this is an aftermarket fuel pump, and some modifications may be required to get it to fit. The overall size is very similar to other brands such as previous generation GSS340/GSS341/GSS342, however the base is slightly enlarged as shown in the pictures. 

Horsepower capabilities? No other intank pump on the market can come close. This pump can support over 800hp using larger than stock fuel lines. This pump can still support significantly more power than a 255LPH pump even when using stock fuel lines.
