I agree with the AR pumps..
just be sure to get the XW with 3/4" inlets..
going to the 5000 psi version with 1/2" inlets is NOT better..
Tank-feed with the largest fittings and feed lines, and filter you can afford..
I'm even suggesting DUAL-FEED THAT PUMP !!..
you'l have MUCH better seal life, and MUCH less of that expensive downtime.
Stick with brass hose barbs, and NO "flow restriction"
BTW.. use the search in this blog to find more detail than you would have imagined.
I've posted a TON of info on this to help folks like you :{)
