Yes this most certainly can be done but it does get a bit complicated. You definitely are shopping in the right place for parts and Surplus Center should have everything you will need including the unloader valve (actually it would be used as a dump valve in this case). That appears to be the very common single stage pump used on many different brands and models of electric compressors and if your motor is the 5 HP Briggs I think it is then it should work OK. In addition to the unloader valve you will also need a pressure relief valve, an idle kick-down control and a back-flow valve to prevent the air from flowing back from the tank to the compressor, this back-flow valve is not quite as important on a gas powered unit but you still should use one. Without knowing the displacement or CFM delivery of the pump it would be hard to say just what speed the pump will need to run but for sure plan on keeping it well below 1000 RPM.
