Was I supposed to have received a diesel fuel filler neck adapter with my ‘21 JLURD?

They supposedly sit next to the scissor jack but my ‘20 shipped without it and had to be ordered by the dealer.

Glad I found this thread, saved me money. Mine was sitting beside my jack in a sealed plastic bag also.

Is it just a plain funnel? I have tried other funnels and none of the will enter the filler

Naive question: My diesel came with the adapter, but why do I need it? Obviously the diesel fuel pump nozzles fit as is, and the DEF 2.5 gallon container has its own extendable/flexible nozzle. What is the purpose?

Two scenarios that come to mind:

1) Using a gas nozzle on a diesel pump.
2) Using truck diesel. Although the nozzle will not fit inside the neck, you can slowly fill if desired.

I use mine when pouring fuel additive into my tank. Guess it would also come in handy if you're out wheeling and need to refuel with a fuel caddy.
I have tried to use a couple of different funnels but cannot get the filler tube open. Is it a special funnel? Can you post a pic of it? Thanks in advance for any help.

I've had to use mine with truck pumps a couple of times. Glad we have it!

Here's some pictures I took, sorry they're not great pictures as I'm at work and it's currently -3° outside haha.

The short answer is yes. It needs to be a certain diameter to unlock the hinge door and allow the funnel neck through.
