i have a 125 shot of nos with a seperate pump what kind of psi should it be set at.

6-7 psi

5-7 psi minimum.To be honest,I don't know if it would hurt to run fuel pressure unregulated or not but I would shoot for 7 psi and run a fuel pressure safety switch set at 5 psi.JMO.That's how I used to set mine up ..That was running a single Holley blue,which I wouldn't recommend.But you ain't got that problem.I'd go thru about three bottles a weekend,playing on the streets :oops: No problems at all.Stupid,but it sure was fun!!!How long is your fuel line and what size?

fuel line will be about 16 ft long 3/8 in size
