No smell but I did re run the both test (Key-on/Engine-off and running with the reference tube removed). Both tests had the same results 54 psi. I wonder if they gave me the wrong FPR.

with the engine RUNING, disconnect the reference hose... it should be in 58. if it is in 56 is ok, but it should be steady, do some WOT, and fuel pressure should stay in the same range , if you have a bad fuel pump it will loose pressure in WOTS.
