Fuel pump replacement guide?

Recently my car started to smell of gasoline while driving and after it was parked. The mechanic at the service station checked it for me and showed me where it was leaking from which was near the gas tank. He explained that my fuel pump was probably fine but that on saturns it had to be replaced as a unit. He quoted me 650. For the pump and 425. For labor. Can't I just get the fuel lines replaced instead or somehow repair the leak. Thank you in advance for any advice you could give.

It's a 6 cylinder 3.5 engine. 2 wheel drive. The area under the car that he showed was leaking wasn't the gas tank but a plastic container near it. My zip is 92262.

Hi again. You know I probably should have said that its a girlfriends
car so when she told me about the gas smell I told her to get it checked. So I wasn't there today when he [showed] her where the leak was. When she told me what was said I was as perplexed as you probably are. It just seems to me that if there is a leak somewhere but the fuel pump is o.K. Couldn't it be repaired directly? What other components of the car could leak fuel? Thanks.

I have been driving my car without any problems. I went to start my car one morning to go to work and it would not start. It will turn over, the lights, radio everything come on. It turns over like it want to start but it will not. I let it sit for two days and when I tried to start it again it started. I was able to drive it for two days without any issues. It was a Saturday night when I got it started so I was unable to take it to the shop due to them being closed. Monday when I tried to start it, it did the same thing as before and not start. This time I had a mechanic come to me and they said it may be my crank shaft senor. I let it sit for almost two weeks. I tried to start it, it did start and I drove it to the mechanic they were closed. Finally got it to the mechanic, they said I just need something on my battery tightened. Everything looked good. The battery, starter, alternator, was working fine. I drove it that day, the next morning it started fine. I went to the gas station put gas in there went to start it and not were back to square one of not starting. All my fuses and fuel pump were checked and were said to be working fine. Any ideas?

[hi neighbor!] Well that tells me what I needed to know. The mechanic was right after all, although his price quotes were out in orbit! You helped me a lot. Thanks so much.
