That line was the vent line for the fuel tank you drilled out thats why pressure stayed up. The gbody with return have 3 hard lime coming off the top of the tank.......good work on your first customer swap.....may wana look into another way to vent the tank though keep grinding bro 💯💪🏾
@drejackson1000 that helps keep pressure out the tank so it breathe kinda like an air filter to the engine too much pressure in tank can cause tank to leak which can lead other dangerous factors
