In search of a IMCO fuel cap (new or used) and/or the size and thread of neck.
Thanks David!Yea, +1 what Barry said! They sell both the caps and the threaded bung in aluminum and I think the bungs in SS. I've bought them when moving filler necks to inside the boat rather than through the gunnels. IMCO is really proud of their parts (read that "expensive" )eek)) but it's good stuff. I've also done business with Tank-it in Havasu and been really happy with their work. Might reach out to them too...
