Do I need fittings and clamps to install this?

Yes. This is bare hose only — you'll need to source 3/8 inch fuel line fittings (barbed or compression style) and hose clamps separately based on your fuel system design. Determine your fitting type before ordering.

Can I use this for fuel injection systems on a modern engine swap?

NBR fuel line works for most street fuel injection setups, but high-pressure direct-injection systems may require reinforced or braided fuel line. Check your fuel pump pressure rating and injector specs first — if you're running over 60 PSI, step up to a rated fuel rail hose instead.

Should I prep or clean the hose before running it?

Rinse the interior with fresh gasoline or fuel system cleaner to remove any factory residue or debris before connecting to your fuel system. Don't use compressed air — it can introduce moisture. Let it drain dry before final installation.
