Diesel fuel cap

Why is everyone obsessed with an aluminum one? Buy the Mopar plastic cap.
Function over form.

The aluminum cap is nice. The plastic cap from Mopar isn't worth the $20 they are asking for it.

I bought the magnetized aluminum one. Looks sweet.

My next step is to JB Weld a small piece of flat steel to the inside of the fuel lid so the gas cap has a place to stick.

Made 3D Printed ones with ABS like Resin. It uses a 4mm x 37mm Oring
and has a place for a 8-32 Flathead Screw to hold on a Magnet. It
requires you to remove the top 1/4" of the internal ribs.

Will update once finished. I will make the STL file available too.

But it functions to keep the dirt out which is all I care about..nobody sees my fuel cap.

Great idea...but. A screw over a fuel filler tube is asking for trouble. (If it's non-magnetic, that is: otherwise, if it comes loose, it'll just stick to the magnet. )

On my third top-off of my DEF fluid, I spilled some into the fuel fill tube. Cr*ppy design. (VW puts the DEF fill port in the trunk.) As soon as that happened, I bought the magnetic green aluminum one. $35 is steep for a fuel cap...but cheaper than water in the lines.

Yours look great. Any chance of using diesel-green plastic???

It is a weird color Green Resin:

I am just using what I have on Hand. I would epoxy the screw and Magnet on as well. I am
trying some Krylon Fusion Jungle Green Paint. I did not leave room for the O-ring with two
coats of paint. So I have some new prints from last night sitting in the printer right now. It
takes about 3.5 hours to print, but I can fit three Caps at a time on the print surface. I have
to find my box of magnets I purchased already. I think they are in a tote i had in my Laramie.
