Im still way up in the air over it. There are a lot of benifits, but also some sizeable drawbacks.
Ive gone over it before, but Ill bring it up again.
4th gen tank allows the tank to regulate the pressure and not an aftermarket unit.
I get a plastic tank thats a bit lighter, but I get the advantage of the bucket that keeps the pump surrounded in gas.
I also have to adapt either the sender or the gauge so that I know how much fuel is in the tank
4th gen tank also gives me an evap canister attached to the tank.
But...i cant use all that fancy stuff unless I go with a total 4th gen dash. The dash has something to do with controlling the evap canister.
I highlighted a very important pat for a street car. EFI does not like to be fuel starved.

The comment about the 4th gen dash required to use 4th gen evap can't be right. I'm going to read the book. I still don't understand why using the entire fuel system from a 4th gen doesn't work for you. My experiences still tell me GM engineers are better engineers than I am.
