John, you will want to go to Andy's Supply here in Boise.
Boise: Alternative Hose Inc. I've bought from them for years, they are very knowledgeable and have the best prices by far. I had a return fuel line on my GMC pickup that got a hole in it and the dealer didn't have their $60 replacement it in stock. I took the bad one to Andy's Supply and they made me up a new one for $10.
