Fuel Pump Questions I'm putting a stock LS3 from a 2010 Corvette in a custom car. I plan to use the Walbro 392 fuel pump which is rated at 255LPH @ 60PSI.
- My understanding is that the LS3 requires 58-60 PSI fuel pressure, so do I need a by-pass pressure regulator?
- Since the LS3 EFI is a returnless system, will the Walbro pump eventually overheat and fail (due to no/low fuel flow to cool the pump)?
- Anyone had issues with the Walbro 392 pump maintaining 60 PSI under full throttle?
