Hello,
I recently purchased an 85 c10. The previous owners had less of a clue than I do, but the tried to make it a "drag" truck. I've noticed some shotty wiring and some MacGyver'd fixes, but there is one I cannot figure out. On the bottom of the 305 engine driver side, there is a valve of some type with some cheap hose from home depot that is capped off. My questions are, what the hell is it for? Where is the line supposed to connect to? And why in the hell would you cap it off?
