Hi - Looking for a locking diesel fuel gas cap + locking DEF cap. Any suggestions? Thanks!

I never found a locking DEF cap so would be interested if anyone has.

I am using this locking fuel cap..... https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Note - my truck is a 2018 model.

I also tried to get one for my 2017 6.7 and now my 2019. No luck so far, Amazon says it will not fit my truck.

I use a Stant 10510D (not the 10501D) locking fuel cap on my 2017 Ford diesel (see sig). It works fine. About $14 on Amazon. Still have not found a locking DEF cap.

Thank you Chris. I will be ordering one. We will be coming to Ft Collins on Sept. 20th for a week to visit my Mom and sister and brother. I'll order one and have it sent to Mom's house. Maybe we'll catch up, Boomer.

Chris - I stopped by a Auto Palace in Kentucky the other day and they had it there in 3 hours for me. Thanks for the info. It's funny that the Ford dealers claim it's not available. Thanks again, Boomer.
