Braided Vs Nylon Fuel Line The 1947 Present Chevrolet
Braided nylon vs stainless steel fuel line. Braided lines are stiffer than rubber lines and are more durable. It bears the sae 30r5 rating and can withstand temperatures of 40 to 212 degrees. Anyone have any opinions on either of these. This stuff has a history of failing and fuel leaks are not something to mess with. I went with teflon rubber for my fuel line both are stainless. Braided hose provides better heat dissipation and better flow which is important when choosing performance car parts.
The nylon mesh however can get dirty and gunked up with contaminates. This was due to reformulated fuel with 10 percent ethanol attacking the rubber line dying it out and causing a massive leak when we turned the fuel pump was turned on. Braided nylon hoses have an inner stainless steel braid covered by an outer nylon mesh to prevent this abrasion. You could also purchase braided hose to fit specific applications. When a bent filler neck hose is necessary wire inserted fuel hose is also offered. I am making a set of 6 an lines for my transmission cooler.

Under no circumstances should you use the run of the mill rubber braided hose for fuel line. Special an type fittings are often necessary with steel braided fuel line. Working pressure is not relevant but wire inserted hose can withstand 50 85 psi depending on diameter. Push lock fitting use hoses with smooth outer skins over braided mesh. The nylon is a bit more per foot but it supposedly easier to make and i like the look a bit better. These types of hoses are typically used with crimp or reusable type an fittings.
