Poly tank

[Spaulding]

Newby here. In the early stages on a 78 20. Rotten tank is out, replacing tank with Moeller poly. Any suggestions on what size will fit mine? Looks as my only options are a 39 gl or smaller.

Thanks

Our previous owned 17 had a poly tank installed. I know the poly tank would be cheaper but suggest going with an aluminum replacement. Sunshine in Florida has made many replacement tanks for CM members. Some disadvantages of poly tank is retrofitting the vent and fill lines and fuel gauge sending unit to the poly tank. Also I have read that you don't want to foam the tank in place.
