Fuel Supply Line: Description and Operation
FUEL FEED AND RETURN PIPES AND HOSES
The fuel feed and return hoses and lines carry fuel from the fuel tank to the fuel rail assembly and back to the fuel tank.
NYLON FUEL LINES
Nylon fuel lines are designed to perform the same job as the steel or rubber fuel lines they replace. Nylon lines are constructed to withstand
maximum fuel system pressure, exposure to fuel additives and changes in temperature. There are two sizes used: 3/8" ID for the fuel feed, and
5/16" ID for the fuel return and are used on the modular sender.
Nylon fuel lines are somewhat flexible and can be formed around gradual turns. However, if forced into sharp bends, nylon lines will kink and
restrict fuel flow. Also, once exposed to fuel, nylon lines may become stiffer and are more likely to kink if bent too far. Special care should be
taken when working on a vehicle with nylon lines.
WARNING:
-
To Reduce the Risk of Fire and Personal Injury: Always cover nylon fuel lines with a wet towel before using a torch near it. Also,
never expose the vehicle to temperatures higher than 115°C (239°F) for more than one hour, or more than 90°C (194°F) for any
extended period.
-
Take care not to nick or scratch the fuel pipes. If damaged, it must be replaced.
