Need Oring for the fuel pump hanger to the tank, please help

[87 GN]

Ok so I have a 80 wagon and I am useing a modified sending unit from a grand national in the malibu tank. The sending unit install's in the tank just fine but its a little smaller in diamiter then the top of a malibu's sending unit.
After installing the sendig unit I pressure checked it for leaks and the o ring from a GN wont seal its almost falling through the hole in the top of the tank.

I need something larger, before I go nuts looking for something does anyone have a correct spare o ring for this tank?

The GN one I have measures 3 1/4" od, Looking at it I need a 3.5" od o ring. Looks to be 3/16" thick.

Thanks, Ed

Too bad I didn't see this earlier, I have an extra, with a new lock ring.

I think I'm ok but when I get home I'll try this o-ring. If it does not work I might take you up on your spare.

I got a box of spares.

May be able to find a workable one and I am in the "philly area". :lol:
