hey, i noticed lately that my analog fuel press. gauge, located on the fuel rail, was reading much different than my digital fuel press. gauge i have in the cabin. Usually both gauges real between 44 and 51 psi, with maybe a difference of 4-5psi between the two. Now the analog gauge is reading about 71-74psi and the digital is reading what its normally been reading since ive had it, about 46psi. i have not adjusted the regulator at all, and its not loose or anything. which one should i go by??

 

I would pull out my fuel pressure tester master kit and rule out the one that doesnt match. but thats me. i think you need a second or in this case, a third oppinion.
