Fuel Pacer
System consists of a vacuum switch, hoses, diodes, and the left front turn indicator light. If manifold vacuum drops below 4 1/2 in. Hg, electrical contacts inside the vacuum switch close, turning on the indicator light, meaning too much fuel is being used by the engine. This system will override the turn indicator. One diode is used in-line with the left fender indicator light from the turn signal switch, and prevents cross-feed to other turn signal indicators. Another diode is used in the feed wire to the fender indicator and prevents electrical feed-back through the ignition switch when the ignition is in the "ACC" position and the hazard flashers are on.
