Caution: Gasoline or gasoline vapors are highly flammable. A fire could occur if an ignition source is present. Never drain or store gasoline or diesel fuel in an open container, due to the possibility of fire or explosion. Have a dry chemical (Class B) fire extinguisher nearby.
Important: Do not apply pressure to the sensor resistor plate or to the float arm. Pressure can deform the these parts, and cause incorrect operation.
