Hello Evom,

I'm installing an AEM Fuel rail on my EVO 8 part of my stage upgrade for the evo. My question is, do i have to get a tune or adjust fuel pressure if I install the upgraded fuel rail? I'm still going to run the stock Fuel Pump and Fuel Injectors. I've searched around and it says that the AEM is a stock like replacement, I just want to confirm before I install it since I won't be getting a tune until I do more modifications.

I'm installing the Fuel Rail first because I'm installing all my gauges and I don't want to splice my Fuel Line to install my Fuel Pressure Gauge. Thanks in advance.

 

No.

 

Anybody else wants to chime in? Looks like I'm going to install it this weekend then.

 

if your keeping the stock fpr the pressure wont change. you can mount a gauge rite onto the fuel rail should have a port for that

 

so the answer is no btw

 

I actually have a Pro Sport Halo Series, so it will mount in the cabin. The pressure sender will mount on the AEM Fuel Rail 1/8 NPT fitting. Thanks for the response guys. I will have more confidence on the install now.

 

no dont have to
