Diesel fuel monitor system, negative pressure type
First Claim
1. A method for separating, detecting and automatically disposing of an electrically conductive contaminate in the fuel of negative pressure type automotive type fuel systems, comprising, passing said fuel through a separating mechanism to separate said contaminate and accumulate said contaminate at a specified point and location, sensing said fuel and contaminate under negative pressure, passing an electrical current through said contaminate between at least two terminals to complete a circuit, the completion of said circuit causing a valve to open and a negative pressure type pump to operate, whereby said pump sucks said accumulated contaminate through discharge means and directs said contaminate to a point of disposal.

Abstract
An improved negative pressure type diesel fuel monitor system that determines a specified level of water trapped in a component of the system and disposed of said water, said water having been separated from the fuel being pumped in the engine fuel line hookup. The system consists of a device to monitor the accumulated water level as it rises in the device, said device also being the facility for separating said water from said fuel and for disposing of said water, said system includes an electrical wiring circuit, connected to the engine run circuit, to operate said device and including a motorized valve to eject collected water therein, a set of logic circuits as part of said electrical wiring circuit, and a combined visual and audio monitor console to record current status of operation of said system.
