3/8 Inch ID Fuel Line Hose 10ft — 300 PSI ⛽

This marine-grade fuel hose delivers a reliable line for automotive and marine fuel systems, combining flexible NBR construction with a 300 PSI working pressure for everyday engine plumbing and repairs. Its 3/8 inch inner diameter and 10 foot length make it suitable for routing fuel in cars, boats, small engines and machinery while resisting oils and elevated temperatures according to the manufacturer.

Key Points

The hose is made from NBR rubber that resists oil, heat and flame and is rated for a wide operating temperature range from -40.0 °C to 125.0 °C. It supports a working pressure of 300 PSI and a burst pressure of 1160 PSI, which helps maintain safety under higher transient loads. The set includes ten hose clamps to secure connections during installation. Consider that while NBR is resistant to many fuels, material compatibility should be checked for specialty fuels or additives.
