The first time you hold an Aeromotive fitting in your hand you will realize that all fittings arent the same. The exacting standards, tolerances and engineering that go into our state-of-the-art fuel pumps are used on all of our products including our fittings. True billet, CNC-machined aluminum, more area and smoother transition from inlet to outlet creates less restriction and more flow with less of a chance for turbulence. Designed to AN and MS specifications, our fittings not only look and perform better, they will also survive the harshest environments.
