do they make?? if not they should
 

do the ymake anything where you can turn your fuel pressure up in the car? I have a Carb setup and when I spray it i have to raise my FP to 8lbs. normally i run it at 5 psi. i wish they made something I could turn or Refrence my FP to my NOS

Adjustable fuel pressure regualtors they make but im not sure if you an use em on a carb. Dont you just change jets on a carb?

I'm don't know much about carbs, but I'm pretty sure that all you need to do is change out the jets.

Yes you can use an adjustable FPR with a carb. Thats the only way to adjsut fuel PRESSURE. Now if you want to adjust the amount of fuel delivered, you change the jets. As far as changing fuel pressure while your in the car and spraying, Ive never seen anything that would do that.

That's why you install the second fuel pump with a wet system. Its setup to flow the requisite amount of fuel needed to go with the shot of juice.
