Maximize the Efficiency of Your Fuel System

Aeromotive high flow one-way check valves are designed to eliminate back-flow with a minimal loss of fuel pressure. Use them to prevent drain back after the fuel pump is turned off, or when running dual pumps and both may not run simultaneously. Just like your other favorite Aeromotive fittings, these are CNC-machined billet aluminum with a Type II bright dip black anodized finish.
