Thread: Loud Fuel Pump

    That picture is clipped straight from Holley's website instructions for the Sniper with Master Kit, my printed instructions are the same. My bet is that somebody at Holley didn't double check their cross reference numbers.

    The instructions for the 12-920 pump referenced in the manual you shared say, "Use a filter that has a filtration rating of 40-100 microns. Use filters that can flow at least 600 pounds per hour (100 gallons per hour) with minimal pressure drop." Probably an oversight. Best to just use a 100 micron filter.
