It is manufactured to SAE J30 R9 performance and produced under ISO 9001 \/ IATF 16949 quality systems for consistent dimensions, pressure capability and fuel impermeability.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this hose stand up to ethanol and modern blended fuels?\u003c\/h3\u003e\n\u003cp\u003eThe SAE 30R9 construction uses a fluoroelastomer (FKM) inner layer and a fuel-impermeable formulation that resists deterioration, hardening and vapor permeation caused by ethanol and other aggressive fuel blends. That means fewer leaks and less odor migration compared with conventional rubber hoses.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eInner FKM fluoroelastomer for chemical resistance\u003c\/li\u003e\n  \u003cli\u003eEpichlorohydrin outer cover to resist weather and abrasion\u003c\/li\u003e\n  \u003cli\u003eDesigned and rated SAE J30 R9 for superior impermeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use this hose for fuel-injection and pressurized lines?\u003c\/h3\u003e\n\u003cp\u003eYes — the hose is intended for push-on fuel injection plumbing and will handle continuous operating pressures up to 300 psi with a high burst rating.
