Fuel Tank: Description and Operation


A specially designed domed fuel tank is used on the EEC system. The dome allows for expansion of fuel and collection of fuel vapors. A fill pipe which prevents complete filling of the tank is used on these special design tanks. A liquid vapor separator is provided to prevent liquid fuel from entering the system. Liquid fuel entering the separator is spilled back into the tank while raw fuel vapors are passed into the lines.
