Oil Pump

Originally it had a Melling M-63HP, High Pressure oil pump. I am thinking of ording the High Volume, but dont understand why it is so much cheeper if it pumps 25% more oil.

Not sure where you're getting your pricing from but I've never see the Melling HV priced cheaper than the standard flow. What engine are you running B or RB. http://www.hughesengines.com/Index/...=&level1=T2lsaW5nIFN5c3RlbQ==&level2=UHVtcHM=
