According to the 1989 flyer I have from Fountain the 33-35 held 160 gallons of fuel. The 1991 35 held 79 gal aside. I am going to guess that the 92-93 35Lightning held the same as the 91,Fountain didn't come out with new flyers every year. Sorry coudn't find anything on the 98 27 Fever. I have alot of stuff including Powerboat Magazine dating back to the mid eighties.
