Holley 12-428 Details

Holley pumps have fueled more performance engines than all others and the Holley line keeps on growing! Holley is proud to introduce the all new Holley Mighty Mite™ electric fuel pumps! They're big on performance, but small in size! They're quiet, easy to install and work with gas, diesel, blended alcohol and E85! A regulator may be needed for carbureted applications requiring less fuel pressure. We recommend the Holley 12-803 or 12-804 fuel pressure regulator.

Features:

  • 12 volt operation
  • 7-10 psi operating pressure
  • 34 gal/hr flow
  • Good for up to 400HP naturally aspirated
  • Reliable solid state design provides longer life
  • Not designed for use on aircraft of any type.
  • Compatible with all fuels and fuel additives (gas, diesel, blended alcohol, ethanol, e-85)
  • Simple 2 wire hookup
  • Self-priming and regulating
