When changing to an adjustable fuel pressure regulator, Where are you guys checking the pressure after an adjustment is made to see what you got?

Thanks in advance

95 C1500 350 TBI

 

You have to install a test port on the line somewhere.

 

Check the tech articles. The factory regulator is adjustible and there is an article that describes how. As for being able to test the presure afterwards I don't know. Just tweek it a little put it back together and test it until you find the best setting.

 

You can tap imbetween the flex lines. Some guys like to have it closer to the TB so they either spend $$$ for hardware and line or they spend 4 bucks on a pipe flare tube, 2 small hose clamps and a couple inchs of rubber line. There is nothing wrong with doing this since the pressure is well below 20psi in almost all cases of TBI tuning.
If you do get a guage, get one that reads from 0-30psi, not the carb version.

 

i bought an inline t......i put it in in place of the fuel filter......screwed in the pressure gauge and did it that way.....when done just put the filter back in

 

Thanks everyone
