May have a possible answer on the 7520 slow loader problem.

A 3/8" ID hose is a little too small for a constant 17 gpm flow.

Yes. Thanks. The question tho, is could 6' of it at 17gpm drop enuf pressure to crack the loader relief valve, hence diverting some of the flow straight to the sump?

I seriously doubt it. There is not enough resistance to cause any significant pressure which could cause the relief valve to pop.
