My engine run in stand worked for years with a 7# electric pump and a regulator set at 2.5 psi for most carbs. Now engines mounted on the stand call for anything from 25 psi to 65 psi for American engines and way high for some foreign ones. Welded fittings into a large (8g) freon jug where it can be pressurized with air through a regulator from 0-225 which is my dry line compressor limit. Jug also has return line fitting so both by-pass and variable voltage systems cam be used. CAUTION: This set up will flow fuel till jug runs dry so both a ball valve shut off and a fire extinguisher are wise. Works absolutely great without a trunk load of different pumps needed.

Some things never change- - - -they just come up with new names. In the early 1950's the dirt track race car Dad ran used a sealed 8-gallon stainless steel beer keg for a fuel tank, and air pressure to force the alcohol/peroxide fuel mix to the carburetor. They ran about 10 PSI in the tank, which was enough to last through a 25 lap main event on a 1/4 mile track.
