Duramax Fuel Filter Replacement

[2500HeavyDuty]

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.

[2500HeavyDuty]

me neither

But your running the risk of breaking yours.

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.

It is true merchant Automotive has the metal ones. But if you break it that day and the dealer is closed (Like a Sunday like mine), and you don't have a spare your SOL. Also something to think about. I know they have metal ones out there but if GM wanted a metal one on the truck thats what they would have put on it. For some reason the engineers wanted the plastic in there. Not sure on a really good reason but there has to be a pretty good reason(I hope).

Well...coming from an Engineer...it was one of the dumbest things they could have done. Actually, its typically the MBA's NOT the Engineers that make the dumb decisions.

You can get a bolt that will fix there to replace the bleeder screw and any hardware store. I don't remember the size off hand, but I have posted it on DP before. When I have more time I'll or some else can look it up.

Good write-up, Danno. I've done these both ways and prefer to remove the fender liner. It just makes it easier to get to things and I don't get my forearms wedged into places.
