fuel pressure dropping over time

this is just not jiving in my mind
right now, pressure is dropping, so im gonna hook it up to vacuum to drop it even more?

(not that i am opposed to trying it, i just dont understand it, is all)

im having a really hard time figuring out if there is a second ported vacuum on my carb
its a proform 750, so basically a holley

it allready has the distributor hooked up to ported vacuum, and that line is T-ed of into the vapor canister purge valve
so i dont know if id want to T the regulator into that as well


i think im gonna swap out the regulator for the old dead head style and see what that does

if nothing else, it will tell me it is or isnt the related to the regulator


I meant when you get the pressure drop sorted out. Then you can get a slight pressure drop at a cruise. You’d be surprised what a 1 pound decrease in fuel pressure can do for fuel mileage.
