  • Fuel System: 1965 commander fuel line

    On my car the previous owner put on a dual exhaust . Right now the sending unit is connected to the metal fuel line with a piece of rubber line. This rubber line is directly above the exhaust pipe. My feeling is this is unsafe and want to correct it. I want to eliminate the rubber hose by either lengthening the line in the sending unit or using a connector to attach the line from the sending unit to the metal fuel line. I also want to install a inline fuel filter near the tank I would welcome any advice . I feel the any connection I have to make should not be directly over the exhaust. Thanks

    I think that I am visualizing your situation. There needs to be a flexible (a little give) line near the fuel tank (between tank and where the line is first attached to the frame), but you can relocate it a little further away so that it is not near your exhaust. It is OK to put a filter prior to the fuel pump, but I would not put it near the fuel tank, unless you are using an electric fuel pump at the rear of the car.

      Thanks for the reply I believe you understand what I am saying . What would be the best way to extend the line that comes from the tank ? Or am I worrying about nothing with the rubber line directly over the exhaust pipe .

        Put your fuel filter up front just before the fuel pump, that way you strain the fuel from the tank and line and keep the pump working. when you re-route the line you have lots of room for a loop of quality hose to avoid hot exhaust, just clamp it so it wont sag down. piece of pie,LOL.

          What is the distance between the fuel line and the tailpipe? You could install a longer flexible fuel line and support it away from the tailpipe.

            Or come up with something to use for a heat shield. Modern cars have the exhaust tucked up pretty close to the chassis, and use heat shield in the spots that need it. Maybe something you could find at a junk yard.

              maybe check to see how hot the end of the tailpipe is? I think the pipe is not that hot by the time it gets there.

                Always a good idea to replace rubber fuel lines every few years anyway, especially with the poor excuse for gasoline being sold.
                Unless something is different on your fuel tank, the sending unit is on top of the tank accessible from inside the trunk. The line coming out the bottom side of the tank is just the outlet.
                Personally, I would replace the section of rubber line with steel as, I believe, it was from the factory. Why take the chance and later wish you had? You feel you need to do something, so do it right and don't look back.

                  Thanks for the responses, I will replace the rubber line with steel . My biggest concern is that the connection from metal to rubber is directly above the tailpipe about 3 inches from it. I am going to try and get the sending unit off and extend the metal line. I don't quite see the need for rubber line from the tank to the frame because I didn't think there would be any flex there. I can see the need for it at the front of the car where the line goes from the frame to the pump. Am I wrong? Thanks again

                    IIRC, the tank is isolated (cushion/spring) from the frame so you should not make a hard connection with the fuel line. Use a modern flexible fuel line. Three inches should be plenty of clearance back near the rear end of the tailpipe where it is not extremely hot. Put some insulating material in between if you are still concerned.

                        Another option you could go with is what I did, replace the plain rubber hose with braided stainless steel line and AN fittings. If it’s good enough for racing it should be good enough for our cars.
                        Plus it looks great.
