Discovered two things:
-There is no fuel pump o-ring

Guess this could be why I'm smelling gas. I'll be replacing that shortly. Could this also cause the car to hesitate/bog? Since the fuel tank probably isn't pressurizing properly?
-There's aluminum hard piping on the cold side of the IC, and stock shitty rubber hose/coupling on the hot side. I already knew this, but the "elbow" coming off of the compressor is bent slightly greater than 90 degrees and it's a little kinked. Could that be a source of my problems as well?
