**** Yup, sounds like a gusher.
Question: did you test at the fuel return line, or at the outlet of the fuel
filter?

Testing at the fuel return line is the proper place to test. The fuel pump
operates against the standard restrictions to fuel flow . .fuel filter,
tubing, and the pressure regulator.
The test results will be more meaningful.

Looks like your problem is narrowed down to the fuel pressure regulator. Are
you planning on replacing it?
We gots to know if we solved the problem!
