The 18-7842 Fuel Pump Diaphragm and 18-7843 Fuel Pump Diaphragm are included in the Sierra 18-7799 Fuel Pump Diaphragm Kit. Sierra products meet or exceed the specifications of the original equipment parts they replace. Precision-built components for maximum performance and reliability. The diaphragm for this fuel pump is composed of medium-weight, square-woven cotton duck - or nylon plies. It will work efficiently in an oil environment because of its oil-resistant qualities. In diaphragm pumps, a composite membrane bends up and down over a fuel bowl. The bowl contains an input and an output, each with a check valve to ensure that the fluid only moves in one direction.

Key Features:

• It creates a vacuum, which draws fuel from the tank into the bowl.
• It provides suction, which sucks the fuel into the pump via the fuel pipe and a one-way valve.
• It will work efficiently in an oil environment because of the oil-resistant characteristics of neoprene.
• They are silent and do not necessitate any new plumbing or wiring.
• It is a high-quality material that provides maximum performance and dependability.
