i have a 97 honda accord-150000 miles. Last couple days hesitated to start-put in premium fuel thinking I might have gotten some bad gas Ran well then this morning hesitated again until I pushed it do

Did they test the fuel pressure? If it's low, then that's not bad gas, just a weak pump. You could try replacing the fuel filter, if it's been a while the old one is likely dirty. Keep in mind if you've never replaced the fuel pump, and given your vehicles age and mileage, you are certainly overdue. The price quoted seems alright, tad high, but not knowing where you are from I can't say for sure. Midwestern prices would be about 400. The tank has to be dropped to get to the fuel pump.

and all the lines are rusted out and need to be replaced , "linestogo"
