Now, lets get a little feed back on the tank situation
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 controling the evap canister.

Now with a third gen tank, I can leave it there, and run either an aftermarket regulator, or run the Corvette fuel filter which regulates the pressure and has a built in return fitting to go back to the stock tank.

Another problem is evap and what happens.
With a 4th gen tank, I really dont know what goes on. There is an evap solinoid mounted to the side of the fuel rail. Vinny said not to remove or possible hazard as in explosion, and with any Evap system its likely that will happen.
Now if I stay with the stock tank, I guess I will have to reuse my old evap canister? But how will that be connected? I gotta start digging around TGO and LS1tech more.
