Rb20det Fuel Pressure Help

[HanBear]

So I've installed a tomei fpr (genuine) and it's reading 0 psi. I thought maybe that the gauge is faulty but the manual gauge I've hooked up is reading the same.

Having said that my car runs fine...

I have no idea how it's running.. But it is..

I've tried adjusting it and nothing. I'm stuck.

I have a forward facing plenum (top part only)

Stock throttle body

Td06

Inter cooler

Adaptronic

550cc injectors

Aem 320lph fuel pump

Please help.

Oh and my charcoal canister is only hooked up to the fuel tank and the lines that go to the plenum are just to atmosphere.

Thank you!

Have you installed it on the outlet (return) side of the fuel rail?

This is what im thinking

EFI cars dont run without some sort of pressure

Reg lines around the wrong way? Gauge on the return line? Something isn't right. We need pretty pictures...

Sweet mod.

[HanBear]

I will post pics tomorrow. But yes I installed on the return side. It's so confusing...

[89CAL]

Not really.......

Pressure in the rail and hose before reg (if applicable)

No pressure (or minimal pressure) after the reg back to tank

[Ben C34]

Its not confusing. No pics required.

The return line has no pressure.

That's a basic fact about efi.
