Product Description

Note for 172, 172A,B,C aircraft models: Only eligible for use with the upgraded Cessna vent assembly 0523552-2. These aircraft originally used 1/4" vent lines, however they may be upgraded to a 3/8" vent line with the installation of the P/N 0523552-2 vent assembly per the applicable IPC.

Due to the size and shape of the fuel vent lines, this product cannot ship via USPS First Class Mail service.

 

Note: The check valve is not included with the fuel vent line.

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.

Installation Tip:
Access to loosen to tighten the vent line in most of the Cessna aircraft is very tight because the tube flare nut ("B" nuts) sits partway in the wing rib. However, with the right wrench, you can normally loosen the nut from the under-wing inspection holes without removing the top tank access skin. The fitting in the tank has indexing flats and will normally not rotate while the tube flare nut is being loosened and re-tightened for the new line. Use caution in starting the nut as the tank fitting is a welded assembly with soft aluminum. Be sure not to cross-thread or over tighten the nut as you can easily strip the threads on this fitting.

FAQs

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?
