Noisey Fuel Pressure Reg?

[sweetr33]

Hi i fitted a sard fuel pressure reg last night onto my r33. Increased fuel pressure to 52psi at idle but now when the ignition comes on to prime the system before engine start up there is a real loud whine noise from the fuel line or reg. Is that normal when u increase pressure past standard?? Freaks me out.

Do you have an aftermarket fuel pump? or a GTR pump? Assuming your car isnt a GTR.

The noise sounds

orgasmic

?

Sounds like just the fuel pump priming if im not mistaken.

Should be fine. But this is based on assumptions

yeah. normal. malpasis are the worst. at least you'l be able to here when your running out of fuel lol

I put my reg on, but if i bump the pressure up to 50psi, she stumbles down low.

Has anyone have this problem

would upping ur rail presure with stock ecu and injectors raise performance?

yeah i have a bosch 040 intank but its definately not the fuel pump priming that a can here. It comes from the front. even can here it humming while its idling too. Cars running on 5 cyls now though so abit concerned am going to check fuel pressure tonight n evaluate the situation. :s
