Question

Vehicle is a 2003 Chevy Suburban 4x4 2500 series with the 6.0L engine.
I'm wondering if anybody has ever seen this before - and if there's anything "special" I should do to make sure it's fixed.
I've posted here before that I was seeing Autoenginuity throw a code related to "fuel flow insufficient" - well apparently that was because the fuel pump was dying. Over the last month or so the truck just started dying on me while I was driving. Mostly when driving on the highway - but as the problem got worse - it would die on side roads too. So I figured that the fuel pump was going bad.
Another problem I was seeing - for years now actually - was that if I filled the tank to Full - it would leak constantly until the level got down to about 1/2 full. I avoided this issue by just not filling the tank past 1/2 or so unless I was going on a long trip.
When the pump started dying - I figured it's a good time to fix both problems. So I finally got the tank out tonite (no thanks to GM assembly line workers who saw fit to put the hose clams holding the two hoses in the rear on with the screw on THE TOP - making it a real beeatch to get off ).
It still had about 5 gallons of gas in it - so I started moving it around so that the gas was around the fuel pump area - and lo and behold - gas starts peeing out from what looks like right around the gasket where the pump goes into the plastic ring welded to the tank. At least now I know where the gas was coming from.
Tomorrow I'm picking up the new pump from the dealer. What I'm wondering is - is there anything "special" I should be looking at here to make sure that this new pump seals up nicely to the tank and I don't continue to get gas leaking out from around that gasket?
I took a look at the old pump and didn't see anything obvious about the gasket which would indicate why it would be leaking.
