ok; i removed the FMU off my car and am getting bigger injectors for my 90 civic si. The car runs horribly now (fucked fuel preasure) and im wondering where most of you tap for a fuel preasure gauge.

I'm thinking about cutting the main line to the fuel rail (after the fuel filter) and T'ing in and mounting a gauge right there; or a short piece of fuel hose and a guage on that.

You guys think that'll work?

 

I wouldn't looks chessey??

tried to install it on ur fuel filter inlet??

there should be a small nut like a 10 or 12mm
and u can install it there seen it so many times

for those who don't buy the regulator...

 

On my CRX it's T'd like you described in-between the fuel filter and the fuel rail. On my hatch, I drilled and tapped the end of the fuel rail and installed it there. Most anyway should work though.
