According to that, with a 20 gpm pump, 1 inch suction line I am right at the lowest mark for velocity for suction lines, if I drew my line straight.

looks more like almost 2" to me....

I would like to see a picture of your clutch pump. I have one for my tracked vehicle project. I don't have a electric clutch for it so I have machined a tapered hub to fit in place of the clutch. Mine only had a 1,000 rpm rating of 10 GPM at 2500 PSI, so I imagine it could deliver 20 GPM like yours at 2000 RPM or so? Mine has a 24ORB inlet and I think 16 ORB outlet. In my case the shaft on the pump is so short I may not be able to use the face mounting bolt holes as they will interfere with the pully. thanks
