Sooooo....Round three stage Moroso it is...You da man...That is very
valuable information to say the least. Do you have a part # for that
pump.
There are (were) a number of mounting ear combinations
available, plus you can make up your own. Just a 1/2" plate. The "O" rings are
in the housings only. Spinning the pump faster with the smaller pressure
section makes for higher volume scavenge.
At 6,500 RPM about 70 pounds is fine. Nice pumps. Simple. Never leaks.
Peterson has a bigger selection of toothed drive pulleys. Belts from any Gilmer
dealer. Or any power transmission company. Gates or Goodyear dealer. Oil
pressure is adjusted at the pump. I would leave in the stock relief valve. So
stock relief set at say 70 pounds and the pump set at 80 pounds.
