Do I need clamps, and what size should I get?

Clamps are not included with this hose. You'll need worm-drive or band-style clamps sized for 1/4" hose at both ends—pick up stainless steel clamps to match the fuel system environment.

Can I use this on a high-pressure fuel injection system?

This is a standard NBR fuel line. Verify your fuel system's operating pressure against the hose specifications—some modern direct-injection setups require reinforced or braided lines rated for higher PSI.

Do I need to prep this hose before installation?

No prep required. Cut to length, slide onto barbed fittings or adapters, and clamp down. Make sure the ID diameter matches your fuel line fitting diameter before routing.
