I fired up the truck and let it idle for about 5 mins. I had a co-worker look at the line that the fuel was leaking from earlier (see pic. this is a snap shot of the motor (pass side) through the wheel well. The circled line looks to be metal tubing, not a rubber hose. When I opened the fuel drain valve, my co-worker said it was not coming from that line. I then proceeded to rev the truck a few times (not above 2k) to see if it would leak. Of course, it didn't. But I would like to know what the tubing is and if I have more than an o-ring problem.
