Ed ... there are a couple of "non moving part" sending units that use pressure to measure tank volume .... and there is another that uses a magnetic field ..... as long as you have unobstructed access to the tank ... saw it at one of the boat shows .... looks real good but its not cheap

Good luck on the trip and have a safe one !!!!!
