My gas tank is leaking around the sending unit. I see MSA and VB don't carry it. Is it possible to find a fuel resistant o-ring of that size? Has anyone tried, and if so, did you find one, and where? Thanks, Victor.

Are you sure MSA doesn't carry it? The current catalog lists that part as [M] meaning that there are multiple versions and you just need to call them with proper car model information. Only the sending unit itself for 79-83 280ZX models is listed as [A] or not currently available.

I got one from MSA about 4 month ago.

My thick glasses didn't work too well this time. I saw orange and assumed it was "A". I'd better order one. Thanks.
