Filling Your Tank (Gasoline Engine) - GMC 1998 Yukon Owner's Manual

Filling Your Tank (Gasoline Engine)
If your vehicle has a diesel engine, see "Filling Your
Tank (Diesel Engine)"
in the Diesel Engine Supplement.
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don't smoke if you're near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials away from gasoline.
The fuel cap is located behind a hinged door on the left
side of your vehicle.
While refueling, let the cap hang by the tether below the
fuel filler neck.
