Fuel tank vent

Ok, so that's 5/8" right? What are you fueling? A container ship engine in your Duster?


It’s for a friend and is going to do nitrous with it. Because of that and the pump is pretty big (Mallory 250 gph) I figured just start with a 5/8 line both ways and only do it once. That’s a pretty good sized pump. But he got a smoking deal on it so now he has it.
