need a blazer expert...

[frostie_122]

I'm putting a lt1 in my 72 blazer. I was going to use the vapor canister line for a return line. Looking at the factory tank I see the fuel inlet and vent, two vents going into the bed floor, out of the bed floor one line going foreward to the canister I think...(I pulled the motor before I looked), and one out of tank foreward to the motor...

My questions: What is the cylindrical tube out of the bed froor that the three hoses are going into? Can I cap all that off and just have the line foreward and return, and the filler and vent? Maybe use the motorcycle vent cap I saw in another post? Not concerended about gas smell just fuel injection functionality.

thanks in advance
