54mm Tube Type Fuel Sender - 54mm Mounting Diameter 500mm LengthThe advantage of a tube type sender is that it uses the least amount of space within a tank, with no worries about float arm direction. The float is contained within the aluminum cylindrical housing, and it rides on two resistive wires that protect it from the 'extreme fuel sloshing' that occurs in many shallow, large or odd sized tanks. VDO tube type fuel senders feature a standard SAE 5-hole mounting flange and can fit tanks depths from 6" (150mm) to 31-1/2" (800mm).Features:Suitable for gasoline and diesel fuelsIdeal for situations where fuel slosh is problematicAluminum flange and housing can withstand extreme environments, where dust or salt water spray are present2-1/8" (54mm) mounting diameterAvailable in 34 standard lengths from 6" (150mm) to 31-1/2" (800mm)M4 stud and .250" spade connections provided with each senderSupplied with neoprene mounting gasket
