Im installing a carter fuel pump and a holley regulator for my street port 12a with a superstreet nikki carb.

I need a fuel guage for fine tuning but I have read that the 15psi ones tend to be inacurate and that I should get a 0-10 or 0-5 psi guage. From what I found they dont make these for automotive application. Where the hell could I get one and who makes one.

Yawpower says that he tested 3 15psi guages and they were all extremly inacurate.

 

First Paul knows what he's talking about, plus I think he sells one for about $45 that he rebuilt to work correctly.

I found that the fluid filled Holley unit T' into the 5/16 fuel line works for intial setup, but do not leave it on under the hood. My experience is the the session out on the race track cooks the gage.

I got mine gage and 't' for 5/16 fuel line from PAW. I have a straight hose, and remove it to check fuel pressure when I get track with the gage/ 't' setup in the paddock. Once happy with the setting, I go out on the track. If the car is running fine, I don't screw with the pressure regulator the rest of the weekend.

I rebuild my regulator before the start of each season since the car has been sitting.

I have the Holley FI glycerin-filled guage also. I have never had a problem with it. It sits fairly close to my exhaust also. It is mounted on my Magnaflow FPR. I checked it against the dyno and it was extremely accurate.

 

i used to use one i ordered from Summit, however those are not built specifically for rotaries and the range is like 1-30. The best guages in my opinion are the Yaw ones. The range on them is 1-5 or 1-10 (i forget) because low fuel pressure is best for the rotary. with the low range, you can see EXACTLY what the pressure is, opposed to squinting to see ABOUT what ithe pressure is with another brand with a 1-30 range.
