Axle Breather Line Extensions

Axle Breather Line Extensions

Part #:

Anytime you lift your Jeep, you need to look at what is attached between the frame and the axles. Things like swaybar links, air or electrical lines to the lockers, speed sensor cables, brake lines, and axle breather lines. All of these need to be either extended, relocated, or modified. Swaybar links and brake lines come with most kits. Speed sensors and lines for lockers can be unclipped and usually have enough length. The biggest thing that we forget about is the axle breathers. If they come off they leave a path open for water and debris to get into the axle. Not a good thing if you wheel in area where you will encounter lot of water. Luckily, they can easily be extended with just a few parts from the hardware or auto parts store.

Additional Parts:
5/16" Fuel Line
Assorted vacuum connectors Vacu-Tite 47307
Zip Ties

Tools Needed:
Utility Knife
Measuring Tape


The parts you need: You can pick these up at most auto parts stores. I found that the assorted pack of connectors was cheaper than buying 2 of the individual 5/16" connectors.
1. Remove the breather line from the axle. Just give it a twist and work it off of the barbed fitting. The rear axle is on the top passenger side from the differential. The front is behind the differential on the drivers side. It's a little difficult to get to.
2. A quick measurement would be to cut an extension equivalent to the amount of lift you have installed plus about 1 inch. The best way it to jack up the vehicle and lower the axle to it's maximum extension and measure the distance between the axle and the end of the breather hose.
3. Cut the fuel line to length.
4. Insert one end of the connector into the fuel line.
5. Insert the other end of the connector into the axle breather line.
6. Connect the fuel line onto the axle fitting
7. Check the lines just to see if you need to zip tie anything into place.

Common Sense and Safety should always be observed when working on your vehicle or doing modifications. Jackstands, wheel blocks, disconnecting the battery are a few of the basic safety precautions that should be used and may not be mentioned in the write ups on this site. You are responsible for your own installation, these write ups are a helpful guideline and should not be taken as an official installation instruction. My write up may be different from the kits currently out there, so alwasy double check the manufacturers installation instructions when installing anything. I try to keep the site up to date with changes that have occured as I discover them, but may not have the latest unless someone lets me know. If you feel that an install is above your capabilities after reading my write ups, I recommend getting together with a club and getting some help. Only a few times have I needed to employe some actual help from a shop to get something done. Usually welding or A/C work.
