Can I use this with fuel injection or just carburetors?

This works for both low-pressure carb systems and EFI applications under standard operating pressure. If you're running a high-pressure direct-injection setup, verify your system's PSI rating first—this line is engineered for gravity-fed and traditional injection ranges.

What fittings do I need to connect this?

The 1/4-inch ID fits standard 1/4-inch barbed fittings and push-lock connectors. Bring your existing banjo bolts or carb inlet size to a local parts counter to confirm fitment before you cut—hose diameter varies slightly by application.

Do I need to flush or prep the hose before running fuel through it?

New hose can shed particles during first use. Flush it with clean fuel or mineral spirits before final installation to avoid clogging your filter or jets. A quick rinse takes two minutes and saves headaches.
