I need a second portable air compressor to haul out into the orchard. So I

Do they make/sell change parts to run an air pump on a small engine? it must
be simple but I'm not sure what is needed.

I had a small Speedaire compresser with a 4 hp Briggs and Stratton
engine. It had only a pressure relief valve that was set for 90-100
psi. The engine ran continuously at constant RPM. When the pressure
in the tank reached 100 psi, the relief valve would vent and release
excess pressure. I imagine that if you were to make up such a setup
that you would want to make sure that the relief valve would be
properly sized so that the compressor pump could not overtake it.
