Billet Fuel Cap for Ram CTD?

[Ron3rd]

Anyone using the aftermarket billet aluminum gas cap with o-ring on the later Ram Cummins trucks? Looks like a good idea to replace the little red plastic cap which can blow away if you set it on the tonneau cover!

They're all over Amazon and Ebay

Got mine today and installed it; it fits and looks great!

Love mine. The fit is nice, here in WI we pump our own fuel so losing the cap would be on me. I saved the "cheap" red plastic cap that came with my truck just in case. :B

Lost mine like that. In Oregon the pump guy opened door n placed cap on my toolbox instead of inside door. I said I will pump and I forgot about the cap. So my OE Mopar cap is a keeper!

And works like a champ, have had mine for 3 years. A four dollar investment is about all its worth considering why its there in the first place.

I bought the billet but the O ring swelled up and it makes it hard to take on and off. This Idea sounds a lot better!

This is a plastic cap with a tether from Mopar. Cost is around 17 bucks.

Yep Bought my truck used and it didn't have the OEM plastic one. I didn't like the idea of the fuel door gasket as the only way to keep water out of the fuel filler neck. I think I ordered my billet fuel cap within 2 weeks of buying the truck.

Ram makes a plastic cap with a tether strap.

Their cap fits snug and overlaps the outside lip of the fuel fill neck. If water gets on or near the cap it should run off the outside of the fuel fill neck.

The aluminum caps look better. I have read of people needing a different size o-ring to make it fit better. Some ship with three o-rings. It really isn't a cap, it is a plug. If the o-ring does not fit snug, water that gets on the cap could still get into the fill neck. I know, there is a second flap in the fill neck to divert water, but I prefer to not depend on it.

I have the exact same thing thanks to MeAgain!

It is what comes on the EGO Diesel. It works great!!!

Thanks Racer, that's probably the cap I'm going to go with.
