Several yrs ago I bought a poly tank for our project "ORANGE" and it's about time to drop it into the rear frame rails! My question to my friends is the tank comes with 3 vent tubes and the truck is a carb. engine not FI so has any of you installed one of these tanks with sucsess and if so which line should be used and which can be plugged off ??
Thanks guys, just want to get it right the 1st time!
Pic.s would be great for me also.........

You basically only need 3 ports...1 large one for the filler neck, 1 for the output to the fuel line, 1 overflow that runs back towards the filler cap. Any additional vents are ok as long as they don't let in dirt. Keep in mind most normal fuel caps allow for ventilation. This might help
