filler neck modification

These restrictors will not vent into the trunk-- I will not do that either. The factory vent tube goes out buy the filler tube where it goes into the tank. They should not change that at all. I have My 66 Valiant 2 dr with new paint this week. I dont want to have that paint ruined. My wagon is very hard to fill also and I will install them on it also. I will post on how they work. My other idea is to weld a washer in the filler tube with a opening to just get the filler nozzle to fill.
