I am having the fuel pick up replaced in my F250. They will be dropping the tank. I want to have the shop do the Harpoon mod so I can get a little more fuel in the tank.
I saw a YouTube video that showed trimming the filler tube off some inside the tank. Do they also need to trim off the same amount of the vent tube inside the tank or leave it alone?
Thanks.

Like Nick said, cut back both tubes. Before I did mine, the pump clicked off with 1 1/2 to 2 gallons to completely full. Now it clicks off about a half gallon away from seeing fuel at the neck.

Did you thought about the hutch mod since you will already be in the tank?
