This is a great upgrade to replace your existing fittings or to add them to a model that doesn't have them! Made of high quality chrome plated brass, complete with stainless components and viton internal / external seals to withstand today's gasoline. The fittings feature duel shutoff valves to block fuel when you disconnect them! Many of the cheap after-market plastic connectors sold elsewhere are only rated for carburetor applications and cannot withstand the pressures of gasoline fuel injection. Ours CAN!
