I fixed mine for under 7.00 with some 3/4inch Black Heater Hose. Take your cracked/broken line off your D2 and if you can save like 3inches of the straight section with the special coupling that goes to the SAI pump.
Then lube up the OEM straight section of pipe with soap or a small amount of WD40, and slide the 3/4 heater hose right up to the flared part of the OEM hose. Then fit a hose clamp and just snug it up. Then cut to length the 3/4 heater hose (leaving some slack for engine movement) and connect it to the SAI pipe with another hose clamp.
Problem solved and no more OEM plastic hose to fall apart!

You don't. I would think something like flare the end after you slide on the proper coupling/reducer/ bushings/ etc. you can find everything you need in copper, brass or black at a well-stocked ACE hardware store
