What years does this fuel cap fit?
▾
This cap set is designed for 2013–2018 Dodge Ram diesel trucks. It fits both 2500 and 3500 models with diesel engines. Always verify your tank size and thread pattern for best results.
Does the magnet work on all truck surfaces?
▾
The neodymium magnet works best on steel body panels near the fuel door. It may not hold securely on aluminum or plastic surfaces. Most Ram diesel trucks have compatible metal around the fill area.
How do I choose the right O-ring size?
▾
Test both O-rings for snugness and seal. Choose the one that fits tightly without forcing. A proper seal prevents leaks and keeps out moisture and debris during driving.
Is the blue cap for diesel or DEF?
▾
The blue cap is the DEF (Diesel Exhaust Fluid) cover. The diesel fuel cap is typically black or gray. Color coding helps prevent misfilling during refueling.
Can I use this cap with aftermarket fuel doors?
▾
Yes, as long as the tank neck diameter matches. The dual O-rings help adapt to slight variations. Confirm compatibility if using a modified or custom fuel access system.
