Rebuilding a Duramax Fuel Filter Head

Common for the older trucks, is the O-rings inside of the filter housing to wear out. Symptoms are where the truck randomly will not start, or run for a few seconds and then shut off. If they are starting to leak, you'll notice it starts to take longer and longer to crank. Simply because the leaking O rings are causing the truck to loose prime.
Double your fuel filtration from 4 microns the whole way down to 2 microns and cut the cost of filter changes in 1/2 with the CAT Adapter for your 01-16 Duramax!

How do you tell if the internal non-serviceable gaskets are good or bad

[@Rustic-N-Rusty]

Thanks for the directional info on the plunger gaskets I couldn’t find that in another video lol. I was second guessing myself

[@JonesBoy6546]

I deleted the whole filter head for like $20, FASS unit installed no longer need that factory garbage. Just put on my cat oil filter I got from ya today. Worked great.

Exactly what mine started doing! This was the first place I was going to check. Thanks for the conformation.

I didnt know about the O ring under the heater plug, had one left over in my kit and figured it was an extra for the bleeder screw...thank you.
