i am lookin to get a fuel pressure gauge what would i need it to go to 0-30 or 0-15 and what should my number look like once i get the gauge

I'd recommend 0-30. If you get a 0-15, your ideal pressure would be in the top 1/3 of the gauge. Or you may peg it at 15psi, depending on your fuel supply.

Plus, gauges are supposed to be more reliable in the middle of their range, so 0-30 puts you right in the sweet spot.

I used to run a 0-15, then switched when I found my gauge sitting past 15 most of the time.

Stock lp only: 0-15
After market supply pumps: 0-30

Actually, I still have a stock LP. But I'm running larger lines and AN fittings and I idle at 16-17.

You've pretty much defined it then. Go with 0-30.
