This Aeroflow Performance fuel pump delivers outstanding performance and durability and is one of the most popular pumps for performance and racing applications. The pump is very versatile, allowing you to mount your pump externally as an in-line pump or internally as an in-tank pump. While producing 300lph (79GPH) of fuel flow and operating at 72.5psi, with this pump you will be able to support 675hp. It features a check valve already screwed into the outlet, if you leave itin you will need to run a banjo fitting as the thread istapered. It is common for people to remove this check valve and screw an adaptor fitting straight into the outlet. If you do this you will need to put an aftermarket check valve in-line to keep fuel pressure in your lines.

Compatible with Unleaded, E85 and Methanol. (When running Alcohol fuels the service life will be reduced, and filter maintenance must be increased).
