Question

What is the fuel tank capacity on a 1978 VIP Boat?

Answer 1

Best would be get it close to empty and fill up to see how many gallons/liters it take. Off hand I will say it 18 gallons if there only one fill hole in back. If, it two up front, one on each side it 12 gallons each, for a total of 24 gallons. But, I just take a wild stab at this.

Answer 2

Grab a flashlight and see if you can find the tank either under the floor or in the stern, possibly in the motor-well (on an inboard).  Most tanks will have an ID tag on them somewhere and it will have the capacity on it as well.  Some boats, especially older models like your's have a section of floor that can be removed to expose the tank for service.  If it were my boat and it had this access I'd remove the screws and pull the tank out of the boat to flush any built up dirt and water out of it, as well as to clean the debris that has no doubt accumulated under the tank over the years.  Sometimes there is an access hatch too, just a round cover in the floor maybe five or six inches across that you can see the tank through.
