Drill a hole into Fuel Filler Neck?
Not sure what you mean, here. I would NOT put it in "lower" and don't confuse "vent" with "return." Hooking your FI tech vent fitting (or is it a return??) to the 1/4" existing line will not vent anything, and will THEN PLUG the only vent for the fuel tank
If you put a fitting (maybe two) into the fuel neck, I would put it up high, refer to how the original "up through" 69 model cars are done..........a fitting up high, and the vent bends clear up to the top of the rear fender, then back down along the back of the filler tube, down through the trunk seal gasket, and ends in the frame rail. THIS IS TO PREVENT siphoning out of a full tank
ALSO if your FItech has a return to the tank (not a vent a RETURN) you want something LARGER than 1/4"........I would use at least 5/16 and consider 3/8. The return fuel should NOT be restricted as this screws up the pressure regulation.
