I installed new fuel tanks on the boat without any sending units installed and no gauges to read the fuel levels. It will be impossible to install the traditional type that installs from the top of the tank at this point. I seem to remember that there is a company that makes sending units that attach to the outside of the tank and will read the tanks capacity electricly, do not want the type that work on air like "Tank Tender". Do any of the members know of this equipment?

As far as I know the outside senders only work on plastic tanks. Seriously you cannot get to the top? How are you going to inspect the fittings? You really have to be able to get to the fittings on the top, if you cannot now I would install an inspection plate or something.

They are saddle tanks, maybe only 4" of clearance with no accomidation for senders when the tanks where fabbed. Was in a minimalist state when I had them built and planned to mearsure levels with dip stick.

4" might be enough to snake one of those Tempo senders the type with a float on a wire rod. Maybe a angle drill could be used to cut the hole.

You might be left with the short end of the stick so to speak lol

ive seen transparent tubes on the outside of tanks on a friends minimalist boat ie proper gauges - depends on location of tank i suppose

bit like this but much smaller

I think I saw what you are looking for at the Annapolis Sailboat Show. They are made by a company called Globius. Got some photos of the setup here:

Scroll down a bit in the post and you will see the units.
