Overview: Fred’s 1997 jeep Wrangler TJ affectionately known as Tubesock was in need of a new engine, and Fred wanted to recreate a crazy stunt from the 50’s by driving his jeep underwater. To achieve this Fred swaps in a new Cummins ISF2.8 diesel engine, bolts on big Maxxis tires, and sets about waterproofing the whole Jeep to survive under 12 feet of water. Will the little Jeep be a submarine or just an anchor? Watch and find out.
