The Walbro F90000267 400LPH pump is one of the highest flowing intank fuel pump on the market, and is E85 safe as well. Walbro designed the pump to meet the requirements of modern turbocharged applications where a single 255LPH fuel pump was severely insufficient. The pump uses a turbine style design which incorporates two composite plastic blades, just like the HFP 255LPH pumps, as well as the Aeromotive 340LPH pump. If you are looking to make big power and are running E85, make sure to consider this pump.
