Fun with in-tank fuel pick up assembly.

My Ex was running out of fuel about 1/8 tank so I dropped the tank to check it out. I shoulda planned ahead and ordered a Motorcraft, but I didn't so when I found the broken foot I grabbed a Dorman locally. With 427k miles I assumed the screens were probably packed full of stuff, but they weren't that bad. I cleaned them out to get a fresh start.

Luckily I decided to test it before re-installing the tank, it was still sucking air at 1/8. There was a lot of back & forth, re-clamped the hose, replaced the O-ring that seals the plastic housing, etc.... In the end I'm not exactly sure what the culprit was but I think it was either the valve on the new foot or the rubber flapper thing on the return. I cleaned both out, re-assembled, and the problem vanished.

I considered the Hutch mod but didn't really wanna deal with the filter install and didn't want to run without one. I did the harpoon mod. I also made a note of where true empty is on the gauge, as well as 2.5 gal, 5 gal., and 7.5 gal. remaining. Good to know just in case.

Sounds good and there are some who have installed an inline 100 mesh filter with nearly no mess, no fuss installation. And calibrating what's in the tank is a great idea.

I just filled up today for the first time, been keeping the fuel low knowing that at some point I'd have the time to drop the tank. The stated capacity is 44 gal and at 22 the needle was nearly exact on 1/2. Many have said you can't actually get 44 in it without repeatedly clicking the pump handle, mine clicked off at 46.2 gal. so the harpoon mod definitely works.
