The return hole is .180in. Id still run a pressure switch if you are running 2 pumps.Can someone measure the stand pipe I.D on the accufab for me? I need to know the ID to determine the flow capability for duel pump/ BIG pump street use. They don't post it on their website. Just take drill bits and see which one slides into the bottom of the regulator. Maybe I should just call them?
kenne bell for me, just my 2 cents
