Need Help, 502 change VST to ?? Pump ??
Hello to all.
I have installed a adjustable fuel pressure regulator on my 502 EFI (MEFI1 1993). I have buy a 502 EFI Kit with K&N Filter, Fuel Regulator, reprogram ECM. Now i have adjust the pressure to 42PSI at Idle with no vacuum hose on it. At WOT (only 4500RPM with 28") it go down to 38PSI. With 44PSI on idle it go down to 38PSI at WOT. Is it normal ?? Delivers the VST Fuel Pump not enough fuel ?? What Fuel pump can i buy to replace the VST and the mechanical Fuel Pumps ?? What are the routing for the Fuel lines ? Tank>Pump>Filter>Fuelregulator>Fuelrail>Filter.... ... Are the Filterbraketfittings big enough for a bigger Pump ?? What pump are the best ? http://www.summitracing.com/search/D...s/?Ns=Rank|Asc |
