Review on 🚚 Dodge RAM TRUCK 1500 2500 3500 (2013-2018) Magnetic Diesel Fuel Cap + DEF Cap Combo Pack for 6.7 CUMMINS EcoDiesel (Easy Grip) by Arunprasath Elliott

Great products install in under 2 minutes. This involved removing the original factory DEF cap from the snap ring and installing a new cap into the snap ring. Other reviewers have noted that the DEF cap does not fit the retaining ring when in fact it does, at least on a 2018 Ram. Take your time. When installing, I simply put one side in the groove and then, using only my hand to avoid scratching, pressed the retaining ring against the new cover.
