Fuel tank vent line?

[0-60n4]

I removed my charcoal canister and want to put a small filter on the vent line near the tank.

I see access is not easy. There are 3 lines from thank to the front of the car, fuel supply, fuel return and vent line. Attached is a picture I took from underneath. The top of the picture is the tank end of the lines. Can someone tell me which line is the vent line? I don't want to cut the wrong one!

vent is the 5/16" line ,return is 1/4" ,feed is 3/8"
the vent is the one on the driverside with the spring clamp on it

If you do this put the filter up front on the frame rail and if you decide to put canister back in your good to go. I removed the canister on my car and when it sat in the garage you get the smell of gas in the shop. I put the canister back in and no more smell. I had a small K&N filter with a piece of hose slid over the line up front
