Go to a wrecking yard and just get another used one? It can't be too much for the whole assembly, fuel pump and sender included. I've bought an entire gas tank complete (including fuel pump and sender) for $75-
Just for reference, fuel pressure under closed throttle should be about 30-35 psi and under full throttle (or zero vacuum) it should be between 35-45 psi.
My 3RZ came out of a T100, and the book called for a T100:
31-37 psi at idle
38-44 psi at WOT
I am using a single turbo Supra (7M-GTE) fuel pump, and the book calls for it:
23-30 psi at idle
33-40 psi at WOT
And my actual reading with my 3RZ and Supra Turbo fuel pump is:
39 psi at idle
46 psi at WOT
