You mean one that won’t co-habitate with an actual cap and the DEF fill?My 2017 Eco had the fuel fill break when it was -30°C the other day. I’m not sure how to fix it exactly but installing fuel filler out of an older truck seems like a better choice.View attachment 126854
BTW the way guys when I posted this on FB no one had a solution. They just told me to wash my truck. It’s nice to be surrounded by witty people whom can solve problems. Thanks! The TDR is the best.
