LDH: You will also need a REDUCTION on that engine. Roller pumps work around 650RPMs. Putting the main filter before the pump is also super important to protect the pump also as their rollers are nylon and easily scared by undesolved and filler trash in a mix. I have a NEW Hypro 252 with reduction gear and regulator for $400 which bolts directly to your engine. Probably about the same cost as a Pump and Reduction Gear alone.
