Agile off-road diff breather

[parb]

Anyone installed it yet?
I ordered a set, seems like it's a decent insurance against a problem I hope I will never have.

Any ideas on the longevity of the plastic hose is? Will it age and need to be replaced every so often like some plastics?

Whether or not the factory differential bleeder valves wiill fail (or not) or cause the pinion seal to leak (or not) getting your differentials vented properly is a very good idea.

The only thing I don't like about the ARB system is that it routes to one location causing a long run of tubing from what presumably will be the rear dif to the engine compartment.

To answer your question, the tubing looks a lot like the polybutylene piping I've been using in my yard for over 30 years to water plants which has a life expectancy 50 years.

I am going to opt for something a bit less elegant in the form of 3/8 fuel line run vertically in to the engine compartment in front and to a high point on the body in the rear to avoid a run of tubing from the rear something like this.

In general (I haven't got the Agile product) the standard hard plastic hose is very resilient.
Not a diff breather , but the hard black plastic fuel injection lines have been spraying petrol into my 1978 911 since 1978.
They live in the engine bay and see sunlight through the engine lid. No cause for concern.
That said, any line under a 4x4 body gets regularly inspected by me for kinks and nicks.

This is my version of the diff. breather. I used a 6 mm compressed air hose, a compressed air distributor, 1/4 inch connections and 1/2 strainers. The holder consists of an old 50x50 mm aluminum sheet with 4 blind rivet nuts. This sheet metal was attached to the original fender screws. Both axle differentials and the transfer gearbox are connected. The fourth connection is for the ZF transmission, but I haven't made it yet, because it's difficult to get to.

nice work.

do you have any photos of the transfercase connection?

See pictures

The breathers from the transfer case and the ZF transmission are directly behind the cylinder head above the clutch bell housing. Both hoses could be ripped out from below, but I didn't want to break anything, so I left them where they are. In order to access the ZF transmission connection, you would have to remove the front drive shaft. Even with an endoscope camera, it was difficult to get decent pictures of the route and connection of the hoses.

How high are they off the ground?

The distribution strip for my breather is approx. 110 cm above the floor. It is attached to the bracket with 2 screws, which can be easily loosened. You can also easily loosen the individual hoses to blow them out with compressed air. I only used spring clamps for the hoses on the axles.
