Submersible Fuel Line Hose Kit. Kit includes 36" of 5/16" Inner Diameter Submersible Fuel Hose and 6 3/8" Fuel Injection Rated Hose Clamps. Submersible Fuel Line Hose is designed to handle fuel both internally and externally, whereas ordinary fuel line hose is only capable of handling fuel in the inner diameter. Submersible Fuel Line exceeds the SAE J30R10 rating and is capable of handling gasoline, E85, alcohol-extended gasoline or diesel, and biodiesel fuel in fully immersed, mobile, stationary and marine applications. This submersible fuel line has been engineered for constant contact with gasoline (and other liquid petroleum distillates) on the inside and the outside. Not recommended for use with straight methanol. Fuel Injection Rated Hose Clamps feature solid, rolled edge bands with a special nut and bolt tightening design and are designed to provide uniform sealing pressure required on fuel injection hoses.
