Here's pics of two different gas caps.
Both are listed at eBay and sellers are stating that their cap will fit to a '70 Challenger under the flip top gas cap.

What do you experts say about these, they are not similar so I assume only the other one will fit to 70 Challenger, but which one?



I know that the original locking gas cap is mfg'ed by B&S and it's totally different than these two ones, but they are sooo rare.
I have one such, but two cars

Pressure-Vacuum is for a 71 and 70 California cars (N95).....Is your 70 an N95?

Also - Are they cheap? Wrong is wrong at anything but a screaming price.

What type of aftermarket gas caps are currently available that would fit under the flip top gas cap?

Anyone knowing if Stant is offering a suitable cap?

Can't tell by looking at your pictures which is which, as far as fit. Like FJ5 Fish said there not right for a E body, why pay big bucks, if they cost a lot?

I believe these are the 2 filler necks for challengers. The one on the left is for a 71 with N95 and like FJ5 Fish said for 70 N95 cars.
Look at yours and see which one you have. The one on the right is used in 1970 without N95 72 73 74.

Then these two after markets fit challengers filler necks and also I beleive some 68 B bodys too?
The one on the right is for the filler necks on the left in the above picture.
See the difference in the distance between the locking tags and the rubber gasket? That's what you have to lookout for.
These caps can be had from Car Quest and other parts places for around 15 bucks , so be warned. Don't have to pay huge prices for a correct funtioning but wrong cap.

This is what they look like installed.

Here's a original one.

Challenger 1,

many thanks for your efforts. Attached are some pics from my nonlocking gas cap and my filler neck. Can you confirm, that the "car quest locking fuel cap 35037" or the equally Stant Part 10571 will fit?

Many thanks in advance.

This is the other style of mechanism for the Challenger locking gas cap.

Both appear the same from the side with the lock.

This cap may still be available, I don't know if the vendor sold it

I have of those original locking caps. I don't use them because the gaskets are cracked and because I drive my cars. More than once have I found my flip lid open and my aftermarket cap locked on my filler neck. I bet folks are looking for those hi dollar locking caps and I'm not going to let them steal it from me.

I bought mine around 2003 and I know I didn't pay 600 bucks for them.

Yeah, original or not, sometimes it makes no sense to pay the price. I just want to have it locked and for a couple bucks, that would be fine.

Challenger 1, can you confirm that the "35037" will fit on mine? Then I will get it for sure, but the 70 Challengers are not listed on Stants side (see above). And I cannot simply drive to the next store and try

And at the end of a day I'm not sure if the filler tube is stock or not, that's why I've attached the pictures.

TIA
Thomas

By looking at your old cap...

Yes the 35037 will fit your filler neck.

I can't see you filler neck to be 100% SURE.

here's the 2 originals that I have. One says pressure vacuum and the other says not vented. No challenger or cuda ever came with a vented cap, none. Matter of fact no mopar came with a vented cap after 1970.


I believe both caps to be made the exact same only with different gaskets just like the aftermarket caps.

See the different gaps from the locking levers and the rubber seal?

Your supposed to have a small amount of pressure in your gas tank on a warm day when you open it, up to 1.5 PSI, your fuel system is a vapor saver and is designed to be under pressure. That way you don't smell gas in your garage or anywhere else.

Thanks for enlighten me and for the pics.

13 bucks here: Stant 10571 Fuel Tank Cap | eBay but also listed as not compatible for 70 Challengers.

Good to know, many thanks.

Challenger1, I think the gasket on your "pressure vacuum" cap is messed up. Here's a side by side with two NOS ones.

Challenger1 - Do you think the gasket on the Stant cap will work on the original mopar locking cap? I too have a cracked gasket. Thanks
