Fuel Filter change
Changed filters today after looking at video and e-mails did not know about check valve as I drained about 1 gal out before reading all.A quetion I have ,when I tightened housing on DFCM it says to tighten till it stops.when i did this it stopped about 1/8 trun past where it was wires would not reach,I backed it till wires reached primed and started truck all seams OK. did take back apart before priming all looked good.Do I have a problem?About 15K on truck filters looked good no evidence of contamination

Tighten until you hit the positive stop. If that happens to place your wires in a bad place, I would unthread and rotate and see if you can catch a different thread so you end up hitting the positive stop.

I did take it off and tried to get it to engage threads at different location.Tried that twice also to check to see if I broke something.Just don't understand if positive stop why connections would not line up.Was only off maybe a 16th of a turn.Is runnig now and does not seam to a problem.Thanks

I did not know about check valve either.When I first drained filter it would not stop draining.Went back and read responses to video.One of them says there can be a problem when tank is over 1/2 full but if you loosen canister 3 turns a check valve will stop fuel flow.Worked for me.I also primed and started truck after each fiter was changed.
