What size clamps and fittings do I need?

5/8 inch ID hose pairs with 5/8 inch barbed fuel line fittings and standard hose clamps sized for that diameter. Clamps and fittings ship separately — verify your carb or fuel pump inlet before ordering.

Can I use this on a fuel-injected engine?

Yes. NBR fuel line handles both carbureted and EFI systems as long as your fuel pressure stays within spec for the application. If your engine runs high-pressure EFI, confirm your system's PSI rating before install.

Do I need to replace this hose periodically?

NBR rubber degrades over time with fuel exposure and heat cycling. If your car sits frequently or hasn't had fuel lines serviced in 10+ years, replacement is preventive maintenance worth doing while you're already under the hood.
