Im planning on putting a fuel and oil pressure gauge in my evo, I got some questions;

They sell a 0-100 psi and 0-150 psi for both of the fuel and oil gauges and I am assuming that there is no way I would need the 0-150 plate because I think the oil pressure at least would never hit 100+psi at wot (but may be wrong) and what about fuel?

Does anyone know if I need any other sending units or misc. parts for the oil pressure or does aem supply the only part I need?

Also where would the best spot to hook up the fuel pressure sending unit? Thanks.

 

Hi there,

The fuel press sending unit will be hooked up to your Fuel Pressure Regulator. Helps if you have an aftermarket unit.

The oil press will be hooked up to where your oil filter is. You might need an adaptor for the sending unit.

Here are my readings:

Cold Idle / Startup
Fuel Press: 35psi
Oil Press: 90psi
Oil Temp: umm...COLD..lol

Hot Idle (after some runs)
Fuel Press: 38psi
Oil Press: 20psi
Oil Temp: 85c

On the road (full boost @ 0.9bar)
Fuel press: 55psi
Oil press: 90psi
Oil temp: 80-90c
