Got the van back last night, and after taking these screens out, all seems good. Maybe a little more vibration at top speeds, but I am attributing that to my newly mount swivel seat and me taking out some of the padding in between the floor and the mount temporarily.
This is how the filters looked inside the tank. Definitely clogged with all sorts of stuff, some that appears to be delamination of the tank.
I did not get the filter between the tank and the pump yet. Any recommendations on that? How hard for the average joe to install?
Good point on the fuel pressure gauge after the filter. I will have that installed when I switch out that filter in 12k miles (or when I get the courage/time to do it myself).
Felt so good to feel that 7.3 power again!
