Wound it hurt anything to vent under the truck.
Isn't that how older stuff pre smog did it?
My tank has a vent in each front corner that would normally hook to the evap system.
Which I no longer have.
I ran them to a T and a single 1/4" line that runs about 3' up the frame rail and caps off because I didn't know what to do with it.
My original plan that I've never done was to basically build my own evap system, by running it to an actual LS evap solenoid mounted in my air box under the hood, that just opens when it's running.
My air box is essentially just a bent plate with PLENTY of gap around it, so it's not going to vacuum my tank in.
But is that even necessary?
Or worth it?
I just don't want a bunch of gas vapor pooling up under it or in it that's going to blow me up when I start it or something lol.
