fuel capacity on 18?

[Tom Bare]

I think I read here somewhere that the fuel tank on the old 18's was in the neighborhood of 36 gallons.

ALthough I have not checked it in years I had always thought I had 48 gallons. I have bought a Navman fuel gauge and would like to know how many galloons I really have at full.

Was there an option for a larger tank on the 18's? It's a 79 model.

Thanks,
