Scuba Mod

Noticed some weeping from the rear pumpkin, and on my last diff oil change I noticed a "woosh" sound upon opening the drain plug...so... Finally got all the parts needed to install the infamous FJ Scuba Mod. Hopefully will install it this weekend. It entails replacing the metal breather on the rear diff and the e-brake with 1/4" fuel line and running it into the rear compartment and attaching it to a mini air filter. Perhaps the current breather is stuck or not functioning, thus causing positive pressure inside the diff..
