Question about fuel lines from tank to fuel pump - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1972SUPERSB · 10-05-2012, 01:26 AM

I noticed one of the lines was capped off at my fuel pump. I'm thinking its the vent hose if these trucks had one? The fuel pump has the feed from tank, then feed to carb them the other is capped off. There is also a hard line coming up the frame from tank that just ends right before the fuel pump, so I'm pretty sure the capped line goes there. Does anyone have a diagram of where all the fuel lines hook up too? I also looked behind seat and saw 2 lines running up passenger side cab? Thought that was pretty wierd. Any help would be appreciated.
