I bought another...1984 4000S quattro for 300 bucks. I towed it home, but drove it into the garage

Not too bad of shape but plenty to do before it's reliable. There is definitely a fueling issue I need to tend to but maybe the pump is just gummed up. I'll throw some B-12 chemtool in there and see what happens.
Tonight I replaced all the frayed vacuum lines with silicone and repaired all the cracked and cobbled wiring I could find with solder and heatshrink. It's looking better already. Gotta get this thing ready for the snow!
