Attention: TDR Forum Junkies 
I got halfway completed removing my dual filter fuel system from Glacier, now I'm fixing up the truck again. It's been years since I've worked on it, and I have a question about a hose coming out of my completed system.
It's a 2 filter system, which Glacier doesn't sell anymore. I have a rubber 3/8" line which comes from a draw straw in tank. This line goes to my mechanical fuel pump under radiator. This has a little fan belt that's run off the balancer, which turns the pump. I have also left the stock electric pump in. This has the stock hardline from where it mounts on top of fuel tank, and attaches to system just below stock fuel filter on truck. The pump supplies plenty of fuel, and since the electric pump is still there, you always have fuel at engine fuel filter. It really only runs when the drawstraw doesn't reach to last couple of gallons of fuel in tank (or when you've opened system)
So the aftermarket system has a 3/8" line going to and coming back from mechanical pump. When it leaves the pump it goes through the dual filter system, and then it branches off. This is where my question is. It has a brass fitting at upper left of picture, does anybody know what that is? Is this blocking fuel for the hose that I have a question about? That hose just ends around near fuel tank and I cannot remember it's purpose. I can't find where it would hook up, at fuel tank or anywhere else. Is this some kind of overflow device, which pressurizes system, but with over pressure allows to dump fuel overboard in some cases? Seems it would work if I just plugged that line after it branches off, but I'm sure it's there for SOMETHING, but I cannot remember what it is!
Left a message for Richard at Glacier, hopefully he'll call back before weekend
REALLY like to get this thing started, and after I get another brake line, it will be driveable (although w/o driver's door, left fender, hood, front bumper etc.
Looks like a great truck aside from where I've wrecked it!
