Fuel heater and fuel contamination detecting apparatus
A fuel heater and fuel contamination detecting apparatus for automotive vehicles, is described consisting of: a casing member in the form of a heating body which comprises a thermoplastic resin and short metal fibers and which forms a fluid reservoir therein; a filter located within the casing member; a pair of terminals embeded in the casing member for selectively heating the casing; a reed switch located proximate to a bottom portion of the casing and being connected to an alarm for activating the alarm upon closing of the reed switch; a float slidably disposed in the fluid reservoir formed in the casing member; and a permanent magnet fixed to the float, the magnet cooperating with the reed switch to automatically close the reed switch due to shifting of the float caused by contamination of the fuel with a liquid.
