- FYI, majority of gasoline-fueled vehicles have in-tank lift pump, so the fuel lines are pressurized between tank and filter and injection system - pressure compresses and expands o'rings for excellent seal
- again, KJ is vacuum, or 'draw-from-tank' system, so o'rings are not as functional because vacuum causes them to contract and shrink and leak air -

Just to be sure we're on same page, I am referring to the new improved upgraded fuel filter head, the cast-aluminum part bolted to the firewall
- the original as-equipped oem version is the leaker
- new fuel filter element\cannister won't help

Fuel manager head should be replaced first due to potential fire hazard - then address tank-connections if leaks continue

yessir we are I'm looking now into reconendations going thru more crd blogs here
