Fuel cap replacements - does generic from Wally World fit?

[dqa]

Looking to replace the fuel cap for my 99.5 Golf, which runs $47 from Impex or $50 at the dealer. (part 1J0201550F)

The Walmart caps all look the same - apparently there is a standard size and thread. But as we all know, VW is not about to let American standards get in the way of their design.

Does anyone know whether the Walmart caps fit?
If so, can I cut slots in it to fit over the fuel door?
Any other ideas?

Green "diesel only" fuel caps as well.

I replaced mine with a Wal-Mart Stant. It's red and fits.

Thanks for the link. I came across that the other day. I wasn't sure whether Walmart carried that particular size. The Stant catalog hanging from a chain in the store surprisingly didn't list VW, so I bought all three, figuring I'd check it out and return the two that weren't appropriate.

Unfortunately, the sizes available at my Wally World were 10817, 10818, and 10825. Meanwhile, the sizes cited in that other thread were 10830d (green) 10835, and 10501d (green locking).

Will generic caps seal? You don't want that since a diesel tank is supposed to be vented. Seems that era of TDI vents through the cap.

I got a green locking Stant marked Diesel from Amazon. Bought the model number listed here and it's been awesome. Only issue is it doesn't have a leash on it, but so far, I haven't managed to drive off without it.
