To keep dirt, water, etc out of the fuel tank.
Gas Cap is not on tight, or the seal leaks and you need to replace the cap.
need vent cap for 2 1/2 gott gas can.
On my Ford Explorer , that is equipped with a locking gas cap , I turn and hold the key while I'm unscrewing the gas cap in order to remove it ( to install the cap I don't need the key , just screw it in place ( and in my case I wait until the cap makes a clicking noise )
If the gas cap tether is broken it can be replaced by removing the rubber plug or rivet that holds the tether in place. A new gas cap will need to be purchased and the rivet or rubber plug will have to be reinserted to hold it in the gas cap well.
1st of all the doors need 2 be unlocked then u pull or push the gas door open and just unscrew the cap
no most part stores will have them
find and remove gas cap, fill with gas and replace gas cap.
The gas cap light will go out automatically after you tighten, or replace the gas cap.
Lift the gas cap cover .. Put the key in the cap and turn it...
The gas cap can prevent vandals from siphoning out (stealing) your gas if you have the type with a lock.
If there is a gas appliance that is being removed, yes definitely have someone come and either cap it or assure that otherwise the gas will not leak out.
I don't know. I need to align the metal locking tabs with the plastic ring on the inside of the cap and don't know how to do it.
