i cant see what you did, but my guess,
put the TEE fitting, in place of the filter., then the gage attached,
34psi min. (41 is par, at sea level and 34 , up on pikes peak) (the higher the altitude the lower is fuel pressure, or the injector flows to much fuel)
if the pressure is 50 to 60 the FPR is jammed, (bad) or return line blocked,pinched or clogged.
if the pressure is way low(it was) then the FPR is bad(stuck open bad) or the pump is no good.
if the shunt test fails,(with return line pinched) then the pump is NO GOOD. (wrong pump , bad, or its sock clogged, or hose inside near it is cracked and leaking inside tank unseen.
that covers them all i think.
