On a recent trip to Cal. , the weird-shaped hose that fits in the turbo line at the input to the air cooler started blowing off. One day I was under the front of the truck several times trying to get the clamps to hold. The hose is about 2 1/2 - 3 inches diam. on the down-line from the turbo and about 3 1/2 - 4 inches at the input to the cooler. The small end is the one that kept blowing off. The T-bar clamp just would not hold it. It seems as if the hose has stretched or something. I finally wound up triple-clamping that end with regular worm-screw clamps and that held ok till I got back home. Anyone ever run into this problem?
