Go to the auto parts store and buy 10 or 12 feet of the correct size hose. Cut it to length and replace it one at a time. I had a similar issue on my 92 rodeo, and I just changed lines and plugs. Changed the fuel filter and drained/cleaned the tank.

I bought mine idling like that though, so that was the first thing I thought to do. Got less than $50 in all those parts, and it idles gret now.
