I beg to differ Norman. A sight "glass" can be easy as pie. Add a "T" to the line and foot or so of tubing. Costs a couple bucks and only takes a few minutes. Instant gas gauge.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.
People need to stop giving me ideas to mental engineer.....I still want a shaft drive option on my smokin smoker!
Exactly correct George. A little piece of rag in the end of the tube keeps gas from splashing out. I do this on all my ultralight planes where seeing level of gas is more than just an idle convenience..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.
You glide to the ground and yer flyin' is donewhat happens if you run out of gas with a plane
Wow, you almost make it sound fun....You glide to the ground and yer flyin' is done
