Fuel Tank specs '79 v20?

[captainbri79]

Hi, i'm new to this great site. I inherited the "family" boat(original owners of a 1979 steplift V20) and interested in replacing 48 Gallon fuel tank to keep her going strong. I've seen the nice specs on the 60 Gallon fuel tank in other threads, but does anyone have specs on a 48 Gallon? or something around 40 Gallons that will fit the space? Any additiona info on tank removal/re-install etc. is greatly appreciated.
