I’ve got the same filter set-up on my 2002….correct me if I’m wrong please, but We don’t have the valve that keeps pressure at the rail on our filter. I can t figure out where that valve is on our cars, or if it even exists. I loose pressure at the rail within 10 min with the key off. Not a huge deal as I usually turn the key to posit 2 and then strap in, giving the pump a second or two to build full pressure.
I don’t know if our cars with this older filter didn’t have a no-return valve somewhere, or if I just can’t find it.
