I have a quetions and where I have to tap in for a fuel pressure gauge. If you are looking at the engine from the front of the car, on the left side of the fuel rail where the fuel goes in I have a earls fitting going to a fuel gauge. Then I was getting ready to put on my aem universal fule regulator and there is an outlet for a fuel gauge. Is it ok it have the gauge on the left of the fuel rail or should I bypass that and only use the one on the regulator?

 

you can just use the one on the regulator it will be fine
