Extending Diff Vent Lines

[michaelwheatland]

I am looking to equip my JK so that it is able to leap across rivers.
One thing I have been told that I have to look at is extending the vent lines (breathers) on my diffs.
Having a JK Unlimited Sport I have a Dana 30 on the front and a Dana 44 on the back.

Can anyone suggest the best materials and location for relocation of these lines?

Pull out your existing breathers, go down to Pirtek or Enzed, get a decent length of hose, locate your front using the same path into the engine bay and the rear in the tail light. You can use existing fittings or buy cheap fuel filters. Very easy to do.

Thanks heaps.

The front diff breather is located on the front left shock tower, just clips on there - easy to see.

The rear is not in the tail light - its attached just above the frame rail on the rear driver side, same clip as the front.

The trans breather comes out of the trans on the driver side - reach up and feel for it - youll see it on the lower drivers side - it goes halfway up the firewall in the engine. It runs parallel to the AT dipstick. It ends behind the engine, a few inches below the top of the dipstick.

The T/C breather hose also runs behind the engine and ends at the same height, but on the passengers side. Then runs on the passenger side/ top of the tranny to the top front of the T/C.

Don't forget the fuel tank breathers, some late model Jeep diesels have two and one is sitting on top of the tank so it needs to be extended up the fuel filler neck (which is where the other one should be).

Any idea what inside diameter hose to get?

Not sure of the size but did cut off a few cm's from the front breather and took to Enzed and their item number is 611-5 & Description is 'SAE 100 LP Push on hose' fits like a glove and got some brass joiners to extend the originals, a lot stronger than the original as you can see by thereinforcement.
