FUEL PRESSURE?
 

I just installed a fuel pressure guage today and I was wondering what normal pressure was and how low is to low?

22 with factory or piston style lp and wouldnt want to see it too much lower than that IMO.

Mine runs 25 to 27 at idle is that ok?I havent ran it down the road yet will it drop running down the road or should it stay about the same?

you want it to stay pretty constant. if it is the stock LP and you have power adders it is hard for it to keep up.

It will drop under load and like turbo said, bigger sticks or fuel upgrades come into play with that also.
