Do you have the float valve installed on the filler neck?
Geno's is certainly way more knowledgable than Amazon when it comes to Ram trucks. I go to them for almost everything Ram.
Another reason I have the Geno's locking cap is so I have one more thing to do before I stick the DEF nozzle into the fuel filler neck and ruin my day. It happens.
Yep, seems like pouring the wrong stuff happens a lot. I have friends and relatives that have put DEF and/or gasoline in the fuel tank. Only heard of one case (plus your case) of something into the DEF tank. Seems like wifey was driving the truck and wanted to return it “full”. She couldn't get the diesel nozzle into the DEF filler, so she got a funnel. Was elated that it only took a couple of gallons to get to “full”,
As a new diesel owner this seems like the most compelling reason to put these caps on. Forcing me to take one more step before actually putting something in one of the tanks probably isn’t the worst idea. That way you have to be deliberately opening one cap or the other and you’d think it would force you to think about what you’re doing.
I almost bought this exact same thing,look like it would be a nice look instead of the plastic red cap,but i dont run a auxiliary tank either, when the red plastic cap breaks or something else happens might buy,thanks for the thread.
BTW, that cheap ass red cap comes from the factory and should be removed and discarded by the dealer. It’s only there to keep dust and crap out of the filler neck while it waits to get installed. It is not a “fuel filler cap”. But I do like the p/n’s provided in the post for (what looks like) a secure locking fuel cap!
2021. The three splines were added for some reason in 2019. Actually the description in Geno's specifies 2019-2022 trucks. Part number GG-EZ45GLC. 2018 and older used a different version of the cap.
None that I have seen. They sometimes clear stuff out at good prices.
As a side benefit of RV hauling fueling up at truck stops makes it practically impossible to mix up diesel and DEF. The diesel fill nozzle is too large to ever think about putting in the DEF hole, and more importantly (when filling up in the semi ’fuel isle‘) DEF can only be dispensed AFTER diesel is pumped and not the other way around. It’s simply a function of the pumps and can’t be bypassed. Then one look at the ‘three-quarter scale’ DEF nozzle and it’s pretty obvious which hole it goes into.
