I didn't think we needed a vent since a stock tank is vented thru the filler tube anyway (in my case, please tell me if I'm wrong). I really didn't want to drill the frame rail if I don't have to.
I'm wondering too (since I already plugged that vent hole) if I could use the sendor unit as a vent, cut the tube off then install an EFI hose on the outlet and loop it around to keep out stuff.
No sending unit but the lock washer thing and gasket were in the box.
