Fuel Gauge Problem
 

I need help. I have a 27 foot Baja shooter. It has a 90 gallon tank. It was determined that the sending unit in the tank has to be replaced. I don't know how deep the tank is. Is it 12 inches or less? Is it between 13 and 24 inches? I plan to try to measure it this weekend. I thought someone out there might know the answer off the top of their head. I have to order the sending unit for the guy that will be installing it. I don't want to open the tank until I get the new one.

Any help would be appreciated. Is there a Baja number I can call to get this information?
