2001 Buick Lesabre Fuel Smells.

I was wondering just how much pressure there should be in the Fuel Line. PepBoy's replaced my fuel line at a cost of almost $500.00 and I kept the line they removed, as they told me that there was a hole in it "Where Metal meets Rubber" and I just cannot locate a leak. I have successfully pressurized the line to a steady 60 Lbs, and it maintained that pressure for ever! I'm thinking that it may require more pressure, however, immersing the entire line, under water, while it is disconnected from the air source, and leaving 60 Lbs in the line, yields no leaks, anywhere in the line. If it's more than 60 Lbs, I will have to find a different compressor to see if I can get it to whatever pressure it should be at... Picture is at 31 Lbs...
