[QUOTE="ZeroDCX, post: 15876058, member: 91953"] You should do a fuel system pressure test both KOEO and KOER. With KOER connect and disconnect the FPR to get a reading with and without vacuum. Specs: KOEO: 39psi KOER: 29psi at idle w/ FPR vac line attached (w/ 22''Hg of vacuum = -10psi), 39psi at idle w/ FPR vac line unattached WOT: 39psi as well. With boost or forced induction, it should increase in a 1:1 fashion over WOT psi. Example: At 10psi boost, fuel pressure should be 49psi at WOT. (Base 39psi + 10psi). Also when performing the KOEO test, the psi reading should hold for a couple hours I believe. If it bleeds down quickly, you have a potential issue in the fuel system. Hope this helps. [/QUOTE]
