Fuel pressure gauge
I just got a FASS stock replacement pump and I'm going to install a Isspro pressure gauge to go along with it. Should I tap into the fuel line between the lift pump and stock filter housing or between the filter housing and the inj pump?
My personal opinion is to get the reading as close to the IP as possible. If you have it before the filter, You'll only get that reading. What if your filter is clogged you could have 15psi on the guage but only have 5psi at the IP.
