with some work you can make a sight glass on the tanks side might be too much work and can be dangerous as you will need to weld in a couple of fittings.
I still want a shaft drive option on my smokin smoker!
I'm thinkin if you run the T empty line up the side of the tank it will stay the same level in the site tube on the outside of the tank be good if it emptied into a breather hole in the gas cap. or had verry little air hole at the end...we had this setup on storage tanks haulin fuel.
what happens if you run out of gas with a plane![]()
You glide to the ground and yer flyin' is done![]()
