Installation
It appears that this kit assumes that the fill neck of the truck is made of rubber, so that the hose splicer can be inserted and secured with hose clamps, correct? My 2014 Dodge Ram 3500 dually has a metal tube descending from the fill-up inlet. I assume that means this kit is not suitable for my truck?

You cut a 4 1/2" - 5" section out of the steel filler tube and install the supplied T in it's place.
I agree, the description on the website could be clearer, but the instructions that come with the kit are extremely easy to follow.Helpful?

What if you don’t have a fuel cap for your truck
1 answer-
ProductExpert23· 2 years ago
If you don’t have a fuel cap for your truck, you can purchase a replacement fuel cap that is compatible with your vehicle. The RDS Diesel Install Kit for Auxiliary Transfer Tank Conversion (Model 011408) includes hoses, clamps, and fittings, but it does not come with a fuel cap.
