Return fuel system w/ current parts?

50 gph 1/4 NPT In/Out. That pump is not considered high performance in a diesel application, as it was meant to be a replacement for the weaker stock lift pumps on the older dodge trucks(99-04). I'd have to agree, ditch the mechanical, and get a real electric pump for your setup. Do you really see 20psi out of that pump? Typically its under 15psi.

LOL I was a dodge diesel mechanic for many a years yes, they were replaced like candy. I have a large card board box full of them. this was one of the better ones.

A trick with these pumps was to take the three screws out of the top and flip the lid over. Clean the screen,new clean surface for the top of the vanes to run on.

this one was one that was replaced and then replace with a WALBRO after market frame mounted pump.

To answer your question, no i didn't test the max pressure. installed it, feed it to a regulator to push 5 psi so the mechanical pump didn't have to pull fuel. It worked.

Now i want to move the return fuel regulator from next to the tank to the eng compartment so the fuel no longer dead ends at the carb.

NHRA don't allow on the fire wall and i just don't like the look of a fexable fuel line returning over the Valve Cover.........
