Try a biocide. Here is one from FPPF. I have never tried it, but it may kill whatever you have growing. http://www.fppf.com/14660 Killem.pdf

They have to get the hole fuel rail gm does not sell just the fprv.

make sure they disconnect the relief line to verify the valve is open. also if it is bad or isn't make sure they do a pump pressure test. this verifies that the pump can actually make 180mpa.
