The perfect repair accessory for damaged, cracked, frayed or worn-out rubber, plastic, vinyl, or silicone motorcycle, diesel, go cart, fuel injection, systems and when replacing the fuel lines and fuel hoses connected to the fuel rails on cars, trucks, or marine engines with cylinder mounted fuel injectors. These work on .55??-.63?? (14-16 mm) size fuel lines (measure carefully). Both the front wheel hubs on many 4-wheel drive pickup trucks and the climate control system on most vehicles work on vacuum and depend on clamps for secure connections. The clamps meet OEM specifications for connecting the fuel lines or fuel hoses for replacement fuel filters or fuel line check valves on small engines. They will also work with many lawn and gardening machines such as riding lawn mowers, rototillers, edgers, tractors, and log splitters. Works well on beer lines and kegerator beer and carbon dioxide lines. Not recommended for use on welding gas hoses. These are precision clamps made from #304 sta
