Have a new problem with the replacement pump after 5+ years. Now when it has a full tank, the dash meter drops to empty and back to full randomly. After it gets below 3/4 tank it acts normal. I am assuming I will have to replace the float device or can I just clean it up if there is some corrosion?

I would try running a few tanks of fuel system cleaner first. It could clean up the contact points on the fuel level sensor and fix your problem...

My corvette's fuel sender acts up from time to time - fuel system cleaner helps.  I also find that putting in Sunoco fuel helps - they must have some nice additives for keeping things clean without need for extra user added additives.  With my corvette, I try to only put in the better brands - Shell, BP, Mobile, and at times Marathon, as well as Sunoco when needed since it seems to be more expensive.

Have you found the Sunoco to have higher octane ratings?  I know there are some, though they seem harder to find these days, that have slightly higher octane options than most stations.

   Well I got the kit in the mail today, so I got busy and re-sized the hole. On the 2500 I guess it's best to pull the back seat out because of the location, anyway that's what I did, "both seats" actually so I could curl the carpet up easier. I made this picture so any other 2500 people will have a better idea where the pump is located. I measured off the back wall and sideways off what I'll call the 3rd reinforcing line from that side of the back. I wound up widening the hole 1/4" toward the center(you can tell I went back to my original line) just to make sure I had plenty of room.  Hope this helps you ICONMIKE.

I've never done a electric pump rebuild before, so this was interesting. In fact the last pump I worked on was mechanical (yes a long time ago). But the parts fit and I remembered how it went back together, yay. The worst part was pushing that new hose on the pump. It was cold here so I borrowed a heat gun to soften it up ( be very careful if you use one of these, stuff will melt before you know it). I put a light coat of grease on the gasket and the metal fuel lines and reinstalled the pump.

  It fired right up and sounded good. I realized I hadn't driven it for a week. I'll do the cover Monday, I'm going for a drive.
  Thanks everyone for all your help.

I can't seem to find the pic of the hole. Can you send to rob3280@live.com? Thanks.

Step one: DO NOT buy gas on the day you're doing the job, do not buy more than 5 bucks at time until you do the job. if your pump gave it up AFTER you filled up; you poor _astard.
