Technical Specifications:

Belt Drives: If you are running a Yates, Danny B, Jesel, or Race Master cam belt drive on your small block Ford, you will need to use pump part number 680-WP173SHD
Distributor Belt Drives: Spacers will be necessary to clear belt drive distributor systems.
Finishing The System: This pump is supplied complete with gaskets and hardware but without the inlet fitting and optional back plate. The fitting needs to be ordered according to the size of the lower radiator hose. A back plate will be required in all applications using a stock-style timing cover.
Amperage draw: Under normal use, the pump will draw 6-7 amps.
Overall Height Dimension: The heavy-duty pump is 6.60' long from the mounting surface to the tip of the pump.
Pump Weight: This application weighs 5.7 lbs.

Additional Notes: The standard 42GPM pump is suitable for normally aspirated engines up to 650HP. Supercharged, turbocharged, and high compression, high horsepower applications should use the 55GPM High Flow pump only. This model does not accept heaters or bypass hoses as a standard.

Keep Your Car Cool... Perfect for 12V or 16V Electrical System

Meziere's 100 Series Electric Water Pump is lightweight and flows 35+ gallons per minute. They are ideal for mild street and Sportsman drag cars. The pump housing, motor cap, and impeller are CNC-machined from 6061-T6 billet aluminum for superior corrosion resistance. The stainless steel impeller shaft runs through a 1-piece carbon-ceramic seal that isolates the epoxy-coated motor from coolant for years of reliable service. The motor has a radio frequency suppression circuit in the motor brush card to reduce ignition "RF" interference. These 100 Series pumps are available with two motor option, standard duty and heavy duty.

The HD (heavy duty) motors provide more power and RPM, increasing flow and pressure over the standard duty motors. HD motors are recommended for street cars and other continuous duty applications (where high flow model pumps are not available). Most pumps are machined with a 1" NPT port(s) to direct water into the pump using one of the inlet adapters that you choose to best suit your needs. Inlet adapters are available in slip-on rubber hose style to AN sizes, inlet fittings are sold separately and not included with pump. Most pumps and fittings are chrome, polished, or anodized. Longer inlets, extensions, and angle adapters also available.

Meziere pumps are American made with pride and quality far superior to any other performance aftermarket company. Don't be misled by the inflated flow numbers and outlandish claims of others. Meziere says what they mean and means what they say. The 2 year, unlimited mileage guarantee and full satisfaction money back guarantee should convince you that buying Meziere is buying value!
