| We usually carry the gas tank filler necks and most of the gas tank hoses in stock for the 70-74 z cars. These are all subject to availability of course, due to the age of the vehicles. These necks are made out of pliable rubber and you should be able to compress the neck with one hand. If you can't compress the one on your car then it has hardened and needs to be replaced. Once you have the replacement neck in your posession, you may have to cut the old neck in a couple of places with a hack saw to remove it from your car. Be sure to remove the inspection plate from the right rear wheel well to access the filler neck. These necks should be installed from the bottom side of the vehicle. Last update 08/10 |
