Ford Mustang 1994-1998 Repair Guide

Evaporative Canister



See Figures 1, 2 and 3

For more information on the Evaporative Emissions system, please refer to Driveability & Emissions Controls of this guide.

The canister is located either under the right-hand front fender, mounted onto the underside of the fender apron (3.8L and 4.6L engines), or under the hood on the inside of the right-hand fender (5.0L engine).

The fuel evaporative emission control system stores gasoline vapors which rise from the sealed fuel tank. The system prevents these unburned hydrocarbons from polluting the atmosphere. It consists of a charcoal vapor storage canister, check or purge valves and the interconnecting vapor lines.

The canister and vapor lines should be inspected for damage or leaks at least every 24,000 miles (38,500 km). Repair or replace any old or cracked hoses. Replace the canister if it is cracked or damaged in any way. Other than inspecting the lines and the canister for damage, there is no periodic maintenance for this item.
