8. ressure pump will pull fuel from the tank through a filter As the filter does its job and collects contaminants the flow is reduced As the flow is reduced the lift pump has to work harder to pull fuel to the engine There is a point where the filter is too clogged to support the flow necessary for proper engine function When there is not enough fuel flow the engine stops Unfortunately a filter is very likely to clog more rapidly in precisely the kind of situation when a reliable running engine is needed most When rough seas toss a boat they also mix up the contents of the fuel tank and more contaminants are likely to find their way to the fuel filter Continuous data to alert system installed on console DigiVac Filter Alert Sensor The DigiVac Model 501 Fuel Filter Alert System not only gives a remote indication but also shows a trend of a filter getting clogged Before the model 501 an operator would have to choose a filter replacement interval that would keep the engine running and frequently visually inspect the engine and filter for debris in the fuel bowls as an indication that the filters may be marginal The Fuel alert allows the operator to constantly monitor the filter status while at the helm and while the engines are powering Digivac 501 series Instruction Manual Page 4 2 0 CONSTRUCTION The instrument is housed in a free standing plastic enclosure It is intended to be flush mounted on the system console in a sta
