    One hp electric = two and a half hp gas.

    You need to know the flow rating of the pump.
    That will dictate the HP of the motor.
    Roughly 4 cfm per 1 horsepower.

    Before you waste any more money on it, have the tank certified. That’s pretty old.
    Do not believe everything that you think.

    I have a compressor from that era. I just replaced the tank as it was getting fatigue cracks. The idea of recertifying the tank is ridiculously stupid, as the cost to do so will exceed the value of the compressor. I looked into it when working on mine. The other problem inherent in thos, I found, is that every other component has the same wear as the other. So when the motor goes bad the pump and tank are not far behind. I replaced my tank and about a month after my motor started smoking. Then the pilot gave up the ghost.

    Also, when looking at pumps, most are rated for a certain cfm at a certain HP, at a certain speed hof the pump). If you can find a 7.5 or 5 horse you can change the size of the pulley to accomodate the motor. Easiest if you can find pump specs for it. It does take a wee bit of hunting to find them though.

    Well, glad i only paid 25$ for it. I'll probably put it in a local auction.
    Thanks for your replies.

    most likely a 3 hp electric should run it, (add a pressure switch on it and either up the unloader, or put the pressure switch a few pounds under the unloader, and if your in a situation where the unit is fast cycling, then put an aditional switch that by passes the presure switch and let the electric run and let the unloader do the work,

    I had set up a compressor that way that had limited storage tanks, and when doing some heavy air usage it was nice to let the unloader pop on and off, rather than the motor starting a few seconds after shutting off, and doing that a few times a min, it worked well,
