I have a friend who is doing some major work on his Formosa 41. The previous owner took out the 60 gal fuel tank and bought a new 24 gallon tank but never had it installed. My friend wants a lot more fuel than 24 gallons. What did you have to do to get the 150 gal tank in? Did you have the tank made, or was it prefab and ready to order?
