:badidea::stop:You DO NOT have to cut the pipe!!!!!!!
Remove the factory line from the top of the tank that wraps around to the solid pipe BEHIND the cooler. You can buy the cheap removal tool for these lines for like $10 at any auto parts store. Get 1/2" hose (IIRC) and mount your pump to the shield on the side of the tank or somewhere else suitable. Then run the hose from the top of the tank, into your pump, out of the pump and on to the solid line. Hose clamps at either end-GOOD TO GO!!
I cut the pipe on my '05. After dropping Simon's fuel tank on his '05 last year to do the SoCal pick up, I found it's WAY easier to just remove that hose and put it in there. Plus you can easily go back to stock!!
