    Miller Big 40 Disassembly Question

    I have a 1971 Miller Big 40 welder with a Continental F-163 4 cylinder gas engine. The gas tank was never drained when the welder was last used (decades ago), so it has congealed gasoline at the bottom of the tank. How big a job is it to remove the tank from these units?

    Thanks in advance.

    Take the hood off and you will see the strap bolts/nuts the need to come off and take the fuel line off the sediment bowl

    Thanks. From what you described, it sounds like the tank is pretty accessible.

    If the dead fuel won't come loose through the chemical/ pressure washer (small chain sliding around the inside)process, have a radiator shop boil it out for you, done it tons of times.
    If you find holes PM me.

    Dana gear - I wanted to go with a radiator shop vs me cleaning it, just to expedite the process. I had also been advised by others that radiator shops provide that service. I should have called the radiator shops BEFORE I removed the tank. I have called multiple radiator shops in northeast Ohio, of the two that will do the job, they both said the cleaning process will reveal leaks, and this will necessitate a coating (sealer) be applied to the tank. Cost for this service is $300. One gentleman mentioned that a DIY tank cleaning that results in unsealed pinhole leaks is obviously not a good situation to have with a fuel tank sitting on top of an engine.
