Haha sure man, just swing by and we'll toss in the new tank, haha!
To be honest I still have all the hoses that route up above the rear axle, there are metal lines and stuff that go through somewhere in the car. I never bothered to yank all that stuff out. Its mounted pretty solid in there. I just hacked off the rubber lines and took out the charcoal canister and called it a day.
The new tank is the same exact thing as the other one except it has a different sending unit. I believe the EEC tanks have three outlets on the sending unit whereas the non-EEC tank has just one outlet. Two were for vents and one for fuel I believe.
I ended up sumping my tank anyway, so I had to plug up the original sending unit line so fuel didnt leak out or anything. I wanted to still use my original fuel gauge so I left the rest of it in there.
I know some Novas had 5/16" fuel line while others had 3/8" fuel line. I think the bigger motors (350, 396, etc) came with the bigger line while the smaller motors (307, 250, etc) came with the 5/16" line. I yanked all that old stuff out too years ago and replaced it with all new 3/8" line since I was planning to drop in a bigger motor. The sending unit line was also 5/16", so I just sumped it instead of buying a new sending unit which was pretty expensive.
The tanks themselves are pretty easy to remove/install. The main thing is to remember to run it low on gas before you drop it, otherwise its a real pain. Dont ask me how I know that though, haha!
