Hi,
I am in the process of plumbing my first Gasoline engine and fuel tank setup.

I am using a 3 line system.

It just does not seem correct/proper to terminate the vent line by just having a piece of Tygon hanging out the bottom of the cowl.

Should there be a filter in the vent line to prevent crud from blowing back up into the tank?

Is there a fitting available to terminate the vent line at the bottom of the aircraft?

Just want to make sure my set-up is bullet proof and avoid any problems.

Thanks,
Ken -MI
