I broke off the nipple on my DPM two years ago, what I did was cut the broken peice out of the hose and use a little super glue to reatach it to the DPM making sure that it was lined up just right. then after it was all set up and wasnt going to move I apoxed the outside of the nipple and the DPM a couple of times to get it good and built up, then I used a peice of wire and stuck it in the nipple to make sure there were not obstructions and I put the hose back on. Works great just like it did before and has not broken off in two years so i would say it works, and is a lot cheeper then a new carb.
