Is it OK to take the rubber line off between the OEM filter canister and cp3 to add a 3 rd filter . What kind of pressure is there....8 or 9 lbs?
Yes it is acceptable, I have one there as do many others.
8-10 psi idle is what you will see with the OEM pump.
Bottom of the OEM filter, isn't there a standpipe in the middle of the oem filter where the filtered fuel exits for the pump? Sure thought there was when i changed the cartridge in the canister.What do you mean by standpipe?
I knew you knewGotcha, yes the bottom of the canister is the outlet.
