## Overview

The Walbro 485LPH F90000274 is a top-tier in-tank fuel pump designed for high-performance engines exceeding 500 HP, capable of supporting over 900 HP at 13.5 volts. Featuring a unique dual-turbine impeller for quieter operation and 20% greater efficiency, it’s fully compatible with E85 and gasoline fuels. This pump offers a high-pressure relief valve adjustable between 15-120 psi, making it ideal for modern turbocharged applications requiring extreme fuel flow and reliability.

## Description

All new for 2011, the Walbro F90000274 450LPH pump is the highest flowing intank fuel pump on the market, and is E85 safe to boot. Walbro designed the pump to meet the requirements of modern turbocharged applications where a single 255LPH fuel pump is insufficient. The pump has an innovative design featuring a single impleller with two parallel rows of turbine blades. The turbine design lends itself to extremely quiet operation, especially compared to Walbro's previous "gerator" pump design that had metal gears which were notorious for a very loud whining noise which could easily be heard over even the loudest aftermarket exhaust setups. The Walbro 450LPH pump can flow anywhere from 15-120psi (the bypass valve is set higher than Walbro's previous fuel pumps, which were around 85psi). 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 Walbro's 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 Walbro 255LPH pump even when using stock fuel lines. The F90000274 requires modifications to system wiring, fuel lines and the fuel module, and should be professionally installed. The blades feed two high-pressure pumping channels, as opposed to conventional single-stage pump that uses an impeller with a single row of blades at its outer edge. This innovative design results in improved hot fuel flow, as well as minimal noise and current use, resulting in efficiency that's 20 percent higher than conventional pumps.

Review: Walbro f90000274 - Compré está bomba walbro, vino en su caja original en perfecto estado, me ha funcionado muy bien, muy satisfecho
Review: Are these really e85 compatible - They say these pumps run e85, I have now bought my 3rd pump because they keep going bad after about 3-4 months. If this one goes bad I will find another brand or option. I am running a very expensive engine and if it goes lean under boost it could be a catastrophe.
