t500hps

Built bigger C.I. out of 500 EFI's. Due to a fuel supply problem I want to add fuel pressure gauges to the boat. I want to use gaffrig electric gauges so they match everything else in the dash (biggest problem will be finding somewhere to mount them). What is the normal operating pressure of a 2002 500EFI and where would a sender be placed in the supply line. I assume after the top mount filter right before the fuel rail that supplies the injectors but is that correct?

Thanks,

Well, the stock fuel pump will pressure up to 34 to 38 psi. As far as the gauge goes I have tapped into the fuel rail at the back and installed my sending units there. I'll have to look at one I have here to tell you exactly.
