Vent lines

[texas69bee]

I have an after market tank with an in tank fuel pump and have never hooked up the vent lines. I’m trying to finish a few things up before she gets put up for sale.
If I’m filling my tank and fuel is coming out of one of the rubber fuel lines currently connected, should that be the one that gets connected to the high one in the trunk?

Who made the tank? You should look on their website, if they have one, about who goes where and what to do. You can maybe check out the site for tanksinc.com. They have some instructions available.

It is a tanksinc setup. Like I said it’s been a while. There’s a vent for the fuel pump and I think the tank itself is vented. It just seems logical to put the high vent tube on the one that leaks gas when it’s to full so it will sit higher than the tank itself ‍

The short tank vent tube goes up into the trunk, the long vent tube that runs almost back to the filler neck goes up to the shock mount.

Short to long and long to short. It does not matter if you are talking in the tank or the car side. Blow air in one of the tank holes to figure out which is long and short.

Is there a way to tell which is short or long without digging into it.
Tanksinc setup… 1 vent from tank and 1 vent for fuel pump
From what I see on there website it says tank needs to be vented higher than filler tube which means to me tank vent is the one inside trunk.

Ya, take the fuel cap off, a flash light and look.
