Reverso uses Marco pumps.

I'd check the connections on the Marco pump for leakage, I believe they are BSPP thread, not NPT, though you may be able to thread in NPT. Everything about BSPP is different: major and minor diameter, thread form, etc. Some sizes are close enough to NPT that you can make it work with enough sealant. All the Marco pumps I have are BSPP. McMaster has adapters if it is a problem.

The brass fittings of the original plumbing threaded right on in there with no sense of early lockup and all is well. Thanks for the thought.
