Distributer 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. This should be ordered according to the size of your lower hose connection.
Amperage draw: Under normal use the pump will draw 11-12 amps.

Additional Notes: The standard 35GPM 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 heater or bypass hoses as a standard.
