Diesel Fuel Filler Cap

[BaldwinScott]

Bean counters are OK with your snow packing around your capless tank, after all it's your problem with water in fuel, if it happens.

If that's their reply then I would say "Wrong Answer"!! They spent more figuring out and making the double flapper gizmo then a fuel cap would cost! When I picked up my truck there also was white crystalized stuff all over. Dealer admitted he spilled some DEF. It is to easy to get some of the DEF in your fuel tank with both fill ports right next to each other, Poor Design!!

I'd rather just have a lockable cap or door.

Agreed. I did the All Sales MFG locking fuel door from Geno's... and a green DIESEL cap.

Photowrite: I have been thinking about the locking fuel door from Geno's. Is it an easy install and does it fit good?

Green cap with magnet. $26 at Amazon.

Yep, pretty easy. Do you read the TDR magazine (you should). One of my recent Still Plays With Trucks columns detailed my installation.

Amazon also has replacement fuel doors, some lock. Not sure how they fasten on.
