  • Reviews


Is your plastic fuel filter canister cap showing the signs of aging? You know, the rounded-off shoulders of the 28mm hex head (that's right it is metric not 1-1/8" SAE). Those rounded edges make it hard to remove the cap. We've also seen the caps over-torqued and cracked. Replaces engine mounted fuel filter cap.

Here is a stylish and functional solution from the folks at Geno's Garage. A billet aluminum fuel cap that fits the 2010 to 2024 Ram 6.7-liter Cummins Turbo Diesel engines.

Includes O-RIng.

Replaces the engine mount fuel filter cap.

Get yours today and make removing the cap easy.

Should have bought as a precautionary measure

I have not purchased this, but wish I had. After following the dealer instructions that the "nut" was 1&1/8", it became stripped on the second filter replacement--both were torqued to the specified newton/meter . Dealership wholesale: $87, after 15minutes of debating, got retail at $70. Would have rather purchased this once, vice the drive (35 miles each way) and haggle with the dealership.

Love It

Much easier to put on and I can only imagine it will be easier to take off, and it looks good.

This cover is great, you can't miss where the filter is now when looking in the engine bay! But I did have to move my tranny cooling lines so it didn't rub.

Great cap the only grip is that there is no groove for the o-ring.

Haven't got a chance to install my fuel cap yet but seems like a really good product well worth the money in my opinion a lot better than the oem plastic caps

This is an awesome replacement for the plastic stock cap that can crack and strip when removing.

Great product

This is an amazing product. Shipping was fast and the glasses and decal were a bonus. I will be purchasing many other items from you guys. Thank you.

Works great but it's a bit pricy for a replacement cap

This cap works great. I had previously striped the stock cap by using a 1 1/8 socket instead of the 28mm. I'm still not sure why it was so tight. Anyway even though it was more than I wanted I went ahead with the billet cap. It worked perfectly and I'm sure my next filter change will be easy. The only reason I'm not giving 5 stars is price.

I was out of service without this part and the team jumped through hoops to get me my parts. Excellent fit and functionality.

This cap is a nice upgrade from the oem plastic. My only issue was that at 22ft lbs the cap leaked. Called the guys at Genos who were excellent as always. I was told to hand tighten only. So after 3 times at 22ft lbs it leaked. Hand tight is the way to go. Just run it down till it stops and leave it alone.

Just Buy It!
