Mines mounted under the radiator, first few wheelies I was accused of running N2O Used for priming and as an accumulator. It doesn't get hot, if everything is working correct there is minimal oil flow during normal running. I use a manual cable operated lever, I always try to remember to build some oil pressure and close the valve each time the engine is shut off so I can prime it on the next start. According to Canton, it hold's about 2 quarts with 10 psi air pressure, though there's likely a quart in the lines just to get to the engine as we also use a remote oil filter.
