Stopped at the NAPA by me yesterday, hoping they could give me something that might work when I get down there (he's an hour away). NAPA guy said there's no way, have to bring in the old line and fittings. Took line and fittings to an Autozone in Kalamazoo (where my kid goes to college), no dice, then an Advance Auto, no dice. They didn't know what they were doing (I didn't either). Finally went to NAPA and he set me up.
Apparently you get a "standard" pipe with 'standard fittings" and use adapters to mate it to whatever it connects. Worked fine.
NAPA is the place to go for people with brains.
We were almost out the door at Advance Auto when I said to my son, we probably should check both ends of the old fitting, I hear they can differ from one end to the other. He checked just cause we had to wait and we found out sure enough, they were different. NAPA guy knew how to deal with it no problem. Autozone and AdvanceAuto fail.
