Installation Details for Installing McFarlane Fuel Vent Lines
The fuel vent line on most Cessna single engine aircraft attaches to a check valve inside the tank to prevent fuel from flowing out of the vent line, but this valve has a weep hole that allows some fuel to pass to prevent pressurization of the fuel tanks. Unfortunately, this weep hole is much lower than the fuel level of a full tank. Fuel will continuously leak out of the vent line until the fuel level is below the weep hole. With the original vent line, you cannot fill the tanks without wasting a lot of fuel.
The Cessna heritage aircraft also have a tank interconnect vent line that allows fuel from both tanks to leak out of the vent. When parked on an unlevel surface, the fuel loss from these aircraft may be many gallons.
McFarlane has solved this problem with a redesigned vent line featuring a unique hump that rises above the top of the tank. Some fuel can still escape through the weep hole and out the vent to prevent pressurization of the fuel tanks. However, fuel will stop leaking once the pressure is relieved, and the tanks will remain full.
Convenient Kits
Kits with a new connection hose (where required) and rubber grommet are also available where applicable. Just add a “K” suffix to the part number.

Frequently Asked Questions
How do I keep contaminants out of my fuel system?
The fuel selector valve works in unscreened fuel. Contaminated fuel can cause selector valve seal damage. When fueling from possibly contaminated fuel sources McFarlane recommends the use of a fuel filter, such as Mr. Funnel or another filtering device, to reduce trash in the fuel system.
I installed the correct fuel vent line per your eligibility and it isn’t fitting, what is the problem?
Do you have aftermarket Monarch fuel tanks installed? We have received customer feedback stating that when Monarch or other aftermarket fuel tanks are installed, McFarlane’s fuel vent line does not fit. There is nothing we can do to solve that issue. McFarlane’s fuel vent lines fit well when OEM fuel tanks are installed. Please review the Installation Tips for McFarlane Fuel Vent Lines.
Why does my new fuel vent line appear to be slightly shorter or longer than the original?
Over the years, there were some variations in the original vent lines from Cessna, and variations in the location of the exit hole in the wing. The vent line can be bent a little for proper fit. See the Installation Tips for McFarlane Fuel Vent Lines.
Do you have any advice for installing a McFarlane fuel vent line?
Yes, please review the Installation Tips for McFarlane Fuel Vent Lines.
