Looking to see what you guys recommend just replaced the tank in my 31 JC twin 110 gallon tanks when I pulled the old vent lines and vents off they went right in the garbage now for the life of me cant remember if the were 3/8 or 5/8

Most are 5/8

James 3/8 will work but 5/8 is better like mike said..when your filling at a high rate like from the fuel truck

If you have one measure your vent fitting, that's what your hose will hook to.
