GMC P Series: Fuel System
Affects GMC P Series · 1985–1987 — about 236 vehicles.
The hazard
Certain P3 vehicles could emit gasoline from the fuel filler when the filler cap is removed. This condition results when the contents of the main fuel tank expand and the pressure increases. In the presence of an ignition source a fire could result. Correction: A new fuel tank vent assembly will be installed.
