I think he is being genuine as he wouldnt bother with looking stuff up if he didnt care. Scott and I see eye to eye on some of the emission related stuff, I want to put cats on my 73 because I hate the smell of the exhaust without them and with the newer technology adding them doesnt hurt the performance that much. Two high flow cats on a true dual exhaust isnt going to cost anythng but high RPM power, something which my BBC isnt going to see too often.

In theory all the EVAP stuff is the same, controlled by the PCM at some point. The newer car is just using more input as to when and how it should be comannded. IIRC the TPI/TBI/MPFI command EVAP under light cruise after the car is in closed loop?
The physical hookup is also basically the same, except the canister is on the tank in the 99-02 cars and in the 3rd gen it was in the engine compartment. I am on the same page here as I left the canister and everything on my 4th gen tank when I put it in. In time I had planned on running the wires to the back of the car and hook the 4th gen canister to the 7730 computer, it is after all just a solenoid that controls this.
The problem Al is that if what is said is true about the cluster you are not goign to be able to get the EVAP to work with or without the 4th gen tank. If this is the case there really isnt too many cons inusing the 4th gen tank instead. If you want to screw the PCM you can swap out the resistor board on the bucket and get the correct value for the level or you can swap out the resistors in the cluster to utilize the 4th gen level and possibly get the EVAP to work later. As far as the lines go the 4th gen stuff almost bolts right in. I think you just need a few different fittings and you can use the 3rd gen hard lines and everything. You would basically just disregard the return line from the 3rd gen and use the stock feed line, and then put a short hose at the engine compartment. Alternatively you can also run a braided line all the way to the front of the car and get more volume if you decide to make big power later. Either way you can do the 4th gen tank fairly easy. If you want to come see my setup as is now you can, or I can dig all the parts up this weekend and try to set it out in mockup. The only part I dont have is the stock feed line from the filter to the engine compartment. IIRC the "T" block from the 4th gen setup screws into the stock 3rd gen filter, you just have to relocate the 3rd gen fuel filter bracket slightly.
I did this a while ago but it really sint rocket science, I think people are overthinking the whole covette filter thing too.
I am also assuming "Pocket" is going to do you r harness now?
