With a fluorine rubber inner tube and epichlorohydrin cover reinforced by aramid fiber, the hose balances chemical resistance and abrasion protection while remaining flexible across a wide temperature range. It’s designed to accept common fuel types such as gasoline, E10–E85, biodiesel and diesel without premature degradation.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this hose handle different fuels and ethanol blends?\u003c\/h3\u003e\n\u003cp\u003eThe hose uses an FKM (fluorine rubber) inner compound that resists swelling and softening when exposed to modern oxygenated fuels. ECO cover material and aramid fiber reinforcement add durability against external wear and pressure cycling. Together, these materials let the hose work with gasoline, E10–E85, biodiesel and diesel safely within rated limits.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFKM inner tube for strong chemical resistance to ethanol and biodiesel\u003c\/li\u003e\n  \u003cli\u003eCompatible with E10, E15, E85, diesel and conventional gasoline\u003c\/li\u003e\n  \u003cli\u003eAramid fiber reinforcement for higher burst and fatigue strength\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat pressure and temperature ranges can I expect?\u003c\/h3\u003e\n\u003cp\u003eThis 5\/16\" hose is rated for 300 PSI working pressure with a 1200 PSI burst pressure, providing a large safety margin for fuel injection systems. Temperature capability ranges from -40°F up to 275°F in continuous service, with short-term tolerance to about 302°F.
