Vapor Tight Tanks and ATG readings

Postby CherokeeUST » Tue Feb 14, 2017 12:46 pm

I was looking through the latest PEI Journal and saw a new article about an old problem.

It seems strange that this issue hasn't been solved already.

What is the question again? If it is getting an accurate reading on a tight tank equiped with a vent stack pressure/vacuum valve working, through a fill tube with a wooden stick? the answer is it can't be done once you start dispensing through a nozzle. What makes the whole ignoration of basic physics so funny is it is only rare these days to find a tank that is actually tight. It is sad that a (perfectly) tight tank has the greatest risk of being OVER filled.

Actually the problem is solved with what's called a "tank stick correction gage. We could suggest a regulation making installation mandatory but we are as the present administration in Washington says somewhat over regulated now.

If we made the vent caps less air tight we could solve this. Just make them so air can enter but not escape.

Drill bigger holes in the sides of fill tubes maybe?
