Thanks guys! yeah it was definitely worth the trouble - hella happy how it turned out.
while the liner cures a little bit I'm getting back the things that are more my speed.
Re-pinned the fuel pump harness to match the WRX tank. Soldered the secondary sender line in series (thanks BRZCory)
Found out it came with a walBRO pump so I'll use that instead of my Sti pump.
Also drilled out the center vent thing. I butchered it cuz i thought the flap was just hanging and I would break it away clean, WRONG. looks like I even damaged a secondary thing just past the larger inlet.
Since its all disabled and plugged anyway probably shouldn't matter but.. oh well.
