Howell TBI fuel pump question
Question...Looking for anyone that is running a Howell TBI set up on a 4.2.
Question what is your fuel pressure if you know, and where did you mount your fuel pump?
I'm only gettting about 11 psi, and when it got to 100 degrees today my fuel pressure gauge started bouncing all over the place. I'm wondering if i have mine mounted to far back. I did mount mine per instructions about 18 to 24 from the tank. I was thinking that I needed about 15 psi..
after searching some posts, maybe 11 psi is not to far off, but still concerned with the the pressure bouncing from 8 to 11 when it got really HOT today +100 . Wondering if I shoudl change to a solid copper line from filter to TBI in place of rubber hose?
