Predator 13HP and GP 47 TS2021 build

Hi Everyone, I have done a pretty thorough search and have not found what I am looking for. I am building a 5.5, belt drive machine and the pump does not come with plumbing. I would like to run a buffer tank with a bypass line back to it, but am having trouble figuring out how to match the specs on an unloader valve to the pump. Any suggestions? Thank you!

Get a PA gear drive, forget about the belts. I have 2 and couldn’t be happier with them

Appreciate the advice, do you have a link for that as well?

You can get any go trapped unloader. The one shined up put up will be fine. As far as belly vs gear u cant help you I only run belt driven pumps I’m sure both work just fine
