Non vented narrow tang fuel cap for a 1970 imperial

[napalm00]

Seems that most of the parts cross references are incorrect. Most parts sites are trying to sell me a wide tang cap.

I need , or at least I think I need a non vented cap with tangs like the GATES 31723. Does that exist ?

Car has an aftermarket tank on it with non stock atmosphere vents.

Not a direct answer to your question, but read this to understand the weirdness in '70/'71 fuel tanks + caps, and maybe figure out how your aftermarket tank's vents should be hooked up.

Hey Dan good to see you off the other forum.

This vent setup is completely custom, nothing like stock unfortunately. Only the filler neck is stock.

I'll check the links , thx thx


To make this a little simpler, I just need something that'll keep fuel from sloshing out of my tank. If a vented cap will still achieve this with the super low filler that the 1970 imperial has, then I'll just use that

Ended up installing a Stant 10806 vented cap works great, thanks folks
