Montauk Fuel Tank

There is currently this (http://www.moellermarine.com/moeller-marine/fuel-containment/12-gallon-high-profile-portable-fuel-tank-630012lp/) tank under the seat. It is very difficult to tell how much fuel is in the tank. Tapping seems to be the best option as the analog fuel gauge is under the seat and I cannot slide it out entirely. Has anyone found a good way to tell the fuel level in a small opaque tank like this? Is there a digital fuel sender that might fit in the existing analog hole? 12 gallons isn't a ton of fuel and although I am carrying a 5 gallon tank with me generally, I am sure if I ran out it would be in the middle of Cape Cod Bay with the entire family on board. Thanks!

All fuel gauges and senders for an above deck (and below deck come to think of it) fuel tanks are far from accurate, especially when you are on the moving water, not level etc. If you want more capacity with a bit better ergonomics consider this model. At the moment West Marine, of all places, has the best price. https://www.westmarine.com/buy/moelle...--11052461 Edited by Phil T on 07/10/20 - 12:42 PM 1992 Outrage 17 I 2019 E-TEC 90, Viper 17 2+ 2018 Load Rite Elite 18280096VT

Then you can see the fuel gauges, and buy another one of those Moeller tanks giving you 24 gallon capacity, which the boat really needs. Maybe you can get my personal website crazy photobucket link to work - Montauk album. Try the slideshow button upper right.

You really want a dual tank set up like Finnegan has. Go here and have them make you a couple with the fuel gauge on the end so you can read it, (D-1212) https://miraxfuelproducts.com/rectang...lar-tanks/
