47–01 Fuel Tank Draining and
Vent Checking
Remove the plug or open the drain valve at the bot-
tom of the fuel tank, and allow the tank to drain until
all traces of water and sediment have disappeared;
install the plug or close the drain valve.
On earlier vehicles with a screw-on fuel cap, remove
the fuel cap and clean it with solvent. Make sure the
fuel cap vent is open. Install the cap.
On vehicles with a quarter-turn fuel cap, check to be
sure the vent line at the inboard side of the fuel tank
is clean and not plugged.
