Replacing the rotted fuel line on a fuel-injected 740 Turbo 700 1986

The high pressure fuel inflow line runs from the fuel filter to the fuel distribution rail. There is a "banjo" fitting at the fuel filter and a compression fitting at the fuel rail. If you had a leak in this line, it would spray to high heaven and you would lose gallons of fuel very quickly

The return line handles less pressure and so a crack in the line will often only drip. The return line begins after the fuel pressure regulator (FPR). The FPR is located at the end of the fuel rail nearest the front of the car.

Buy a Haynes manual. It has clear pictures and is well documented.
