    Fuel flow issue

    Ok, so here is my issue. Fuel tank drained and refueled, rebuilt 4 bbl carb, new fuel pump. Tried to start after a month, no fuel flow showing after fuel line disconnected at fuel pump. Let me know what you guys think.

    My guess is that the fuel sender is clogged. Try blowing into the line going to the tank. If you can't blow into it you will have to remove the sender. If you can blow into it try priming the line and pump by pouring gas into it.

      I think you're missing a whole lot of background information. What's the story?

      Is the tank full of varnish from old gas that evaporated away? Is it full of rust? What about the filter?

      In order to give any advice we need to know what's really going on.

      Normally, a good tank with fresh gas has no problem getting to the fuel pump. - Dave

        Dave is correct. If you are trying to reuse a 50 year old gas tank all you are going to do is clog up your new fuel pump and newly rebuilt carburetor. Everyone on here will tell you that a new tank is the best investment you can make.

          Info

          A little more info, the gas tank has been pulled cleanedand re-installed. The fuel pump also replaced, and also fuel filtee. I noticed that there was no fuel going into fuel pump. I removed line going to fuel pump, after several attempts there was no fuel going to pump. Hope this helps a little. thank you for the help

            We had one member who had a pinched hose on top of his tank. Anything is possible. Personally, I would get a long temporary hose, connect it at the outlet tube on the frame by the fuel pump and blow through it... see if it flows to the tank. You can tell if it's plugged. Gas should flow easy through that line. Air should go even easier.

            I hope this helps. Check the hose on top of your tank for kinks or pinch points. - Dave

              By 'sender' I assume you mean outlet from the tank?

                Yeah, Tom. He's talking about the pickup screen in the tank. On some cars, the gauge sending unit, vent and fuel line pickup are one in bundle. - Dave

                  Dave is correct. On 64-66's the sending unit has the pickup tube and screen all in one unit.

                    Is there a way to get to the sender without having to drp the gas tank.

                      The sender is accessible from underneath. You don't have to drop the tank. Just follow the fuel line and you'll find it.

                          Anyone have a good price for a new gas tank?

                          What are your opinions on cleaning out old one with or without coating it?

                            Don't waste your money or your time. Get a new tank from rockauto.com and don't forget to enter the code to get your 5% off. - Dave

                              I dropped the tank and I wanted to see the condition of the fuel line. I followed it to the wheel well and then I noticed the fuel line kind of goes into the frame. Its rubber hoses and I want to replace it. Any ideas how to get to it?
