This fellow has some good ideas on his site.

A sight glass doesn't have to be on the tank itself. If you have anyplace to tap into the fuel line you can T off with a vertical section of tubing that is vented above tank level and it will show the level of the tank in service.Old Stone wrote:That's what I was afraid of.
The tube has to be vented or it can't work.Old Stone wrote:...*just run a clear loop to the top height of the tank top and return it to a T next to the other. The fuel will find it's level but won't interfere with the flow and it will be a sealed system at the same time.
If you tee into the supply line to the engine, it will become a source for air into the diesel supply if the you run the engine and by accident leave the sight glass valve open or if the valve leaks. Air in diesel is a sure way to make your engine behave erratically and ultimately* stop.RickB wrote:

If you have access to fuel valves to isolate*each tank you can use one glass and read any tank you've got. The glass can be at some convenient location on a bulkhead if you want.
