Topic: 69 Pop open Gas Cap

[Kiwi428]

Hi guys,
Has anyone stripped down an original pop open cap and had it rechromed? The center sprung loaded gasket holder is a puzzle to take off without possibly destroying the center peice?
Any help appreciated?

Cheers John

      I discovered the same situation.  I bought a reproduction assembly used the outer chrome trim ring ,  swapped few other parts , and used my original gas cap.  I was unwilling to take the OE gas cap apart and instead reused it.  I have more confidence in the fit and sealing power of the OE cap over the repro set up.  It was cheaper to get the after market pop open gas cap assembly, $100, than to get my OE re chromed.  Brian

Someone used to make replacement center sprung pieces that you bought a kit in pieces so you could Crome yours and use the repo parts to put it all back together or to convert the ones they used to sell without the center sprung part
I have taken them apart but you have to sacrifice the center cover of the sprung part

Cheers guys, I thought as much. Shame, it would have encouraged more of us to keep OE gear on your car? Tossing up whether to give mine a good polish to see how it looks, got a couple of  small chips around the outer ring.

Thanks for the heads up anyway.

My repro 69 mach1 gas cap from NPD looks and functions like the original. I'm very satisfied with it.

I bought a new popper and re designed it.  The problem with my new one is that it would not seal properly. As you push the cap closed the spring must depress to form a good seal against the tank spout or the cap will shower fuel out on hard throttle with a full tank. 

I dismantled it and with the help of a good hardware store I changed the design so it would work.  The chrome and appearance of my new one is perfect and cost me 130.

I still have the original one.  To restore it one must cut it apart, chrome the parts required, then epoxy or otherwise reassemble.  As I recall, the originals we're staked.

The replacement popper has no identifying symbols whatsoever either on the box or on the part.  But it is beautiful and fit perfectly, no warps or other weird fitment issues.
