A premium solution designed for both gravity-fed and pumped installations. Comes with swaged stainless steel full ferrules and BSP hose tails sealed with 'O' rings. Available by the metre or in coils based on your requirement. Non-permeable tank truck drop hose rated for gasoline, kerosene, diesel fuel and biodiesel blends in gravity flow or medium suction. Features a rigid counter clockwise helix for easy slide, plus a built in static grounding wire. The fuel line is a vital part of the vehicle's fuel system. It transfers fuel from the fuel tank to the engine. There are several different types of fuel lines available. The type of line you use depends on the type of fuel and fuel injection system. Metal lines are usually the best choice for a high-performance car. They are durable and can handle the high pressures found in an automotive fuel system. However, they can be expensive to replace if damaged. Rubber hose is inexpensive but degrades quickly and can leak fuel vapors into the garage or cockpit. It also is susceptible to cuts and nicks. A better option is a PTFE lined hose that has a braided stainless or braided nylon exterior. This hose is more flexible than standard rubber and can be secured with AN Hose Fittings. It also can be rated for high-pressure applications. AN fittings have male and female threads that match the size of the hose. The Society of Automotive Engineers (SAE) creates standards for fuel lines and other parts. These standards include dimensional requirements, pressure ratings and type approvals. Quality fuel hoses will have the SAE lettering stamped on them. Look for the letters "SAE 30R6" or "30R7" and a number. This will tell you the working pressure and vacuum rating, chemical resistance, permeation and temperature range of the hose. The best marine fuel hose has a polytetrafluoroethylene (PTFE) inner liner. PTFE is known by the brand name Teflon and doesn't react to alcohol or modern fuel additives designed to boost gasoline octane levels. It also resists fuel permeation and holds up well to high working and pressure ratings.
