DAP, The correct high volume pump for your application is the M155HV, it will have a 3/4 inch pickup tube instead of the 5/8 inch tube used on the M-55HV. Thanks

I have used this pump many times my engines run about 60 to 70lbs cold about 40 to 45lbs warm at 1000 rpm and about 50 to 60lbs at 2500 rpm I also block the bypass for the filter so all of the oil has to go through the filter hope this helps

William, the spring that comes in the pump is a 70 PSI bypass, the pump will also include a 60 PSI bypass spring in the box if you want to lower the bypass pressure. Thanks
