    Anybody have a good source for these for an 05? I searched the old, closed threads and no luck. I can only find one tube, a Dorman part 626-321 for the tee that goes under the manifold. Online Dodge parts nor the Cummins parts site are of any help. Cummins had 3947920 and 3963750 but no illustrations. One of those "tubes" costs over $500! Can't figure out what on the engine would count as a tube and could cost that much.

    That would be the one that runs around to the heat exchanger, stupidly priced. Easier and cheaper to have a hose built.

    I just bought a couple of these from Cummins, and reasonably priced. Can you post a picture of the exact tube you're looking for? I can give you the correct price and p/n. I deleted my trans cooler, so I replaced the metal tube for that setup with the one used on manual transmission trucks.

    Right now I know 3 of the 4 tubes need to be replaced. There is another tube under the exhaust manifold going toward the front of the truck that I haven't inspected completely yet.

    The one going around the back of the block to the trans cooler shows 68149258AA and it has a note that it changed from metal rubber assembly to a molded hose. $100 retail. I don't see the metal line that goes behind the turbo listed, but I know I have seen the short rubber one that always leaks listed before.

    Thanks guys. I might be going the route Steved did and bypass all that stuff with just hose. I found more part numbers and some prices online. Who would have thought some tubes and hoses would add up to several hundred dollars (and that is without the $500 tube)!

    right front tube 3963750 $500+
    right rear tube 3947920 $? (dorman 626-321 $40)
    left rear tube (behind block) 3966225 $72
    left front tube 3957965 $?
    90 deg hose elbow 3967418 $? (4 reqd)
    spring clamp 3931545 $5 (8 reqd)
    right rear straight hose coupler 3820663 $30
    right front straight hose coupler 3967022 $13
    spring clamp 3930310 $6 (4 reqd)
