Your more than welcome to post pics of how u change it from the top.
Oh no Danno...that's a good write up and most will do it that way. To change it the way I do you have to have two hands that work really well and some dexterity.

I mostly did it the way i did for people who want to try and do it them self for the first time and give them a lot of pictures and make it as easy as possible to remove he filter without bumping into anything and breaking it...



and not have to wait 2 hours for the dealer to do it

Just be careful when tightening down the bleeder screw that you don't break it! The truck will not start and it is a Dealer only part. Not cheap!!!!!!
i believe merchant automotive sells a metal replacement for the bleeder screw, and u can use just a regular flat head screw driver

1/2 inch or 13mm nut driver works perfectly on them, just be gentle. ima see if i can find a torque spec on it....



nope there isn't one, they don't even tell you to bleed the air out after replacing the filter in the service manual

I tighten my stock unit with my fingers and I've never had a leak.

I never touch the bleeder screw. Just prime it, start it, it'll die, repump, restart, all is good. Never risk breaking the screw when it's never touched.
