Restore, upgrade, or completely overhaul your fuel filter head with the Merchant Automotive Fuel Filter Head Rebuild Kit for 2011–2016 GM 6.6L Duramax LML trucks.
Choose from three kit options: Seal Kit, Deluxe Kit, or Master Kit, to match your needs, when you're doing routine maintenance or a full refresh.
- The Seal Kit includes everything needed to stop pesky fuel leaks and keep your filter head functioning like new, featuring all the essential seals and O-rings.
- Step up to the Deluxe Kit and you'll get the full seal set plus the Merchant Automotive aluminum bleeder screw and Water-In-Fuel (WIF) sensor delete plug, replacing the problematic factory plastic components with durable, precision-machined aluminum for long-term reliability.
- For the most complete solution, the Master Kit includes all of the above along with an OEM ACDelco fuel filter and a 16oz bottle of Merchant Automotive Diesel Fuel Treatment, perfect for those who want a comprehensive refresh and better filtration performance.
Wondering about deleting the factory WIF sensor? The OE plastic sensor has a history of being inaccurate, brittle, and prone to damage during filter changes. Merchant Automotive’s aluminum delete plug eliminates those issues without triggering any warning lights or affecting your truck’s warranty. Just be sure to use a metal-body filter like the ACDelco for proper fitment, as some plastic filters may not seal correctly with the rigid aluminum threads.
Whether you're just fixing a leak or going for a full-on upgrade, this rebuild kit lineup gives you reliable options to get your Duramax fuel system running clean and strong again.

Overpriced but effective.
Color: Cream
I happened to get lucky and get a warehouse deal at an additional 30% discount. Even at $25, it feels a little overpriced. But it was easy to assemble and serves its purpose. If you line the Velcro up exactly, the panels sag, if you stretch past even, but where it still grips, they look pretty ok. It is very light and does fold very compact for easy storage.

Great price for a great product
Color: Coal Black
Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad

No.
Color: Coal Black, Color: Coal Black
This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

You have to add weight to it
Color: Coal Black
It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy
