The Holley Sniper is working great so far. I have not experienced carb icing. Mileage is consistent at 14 MPG.
I do have one issue, the Holley in tank fuel pump is loud. Fuel pressure is a solid 58 PSI as indicated on the fuel pressure gauge located at throttle body. I’ve reviewed the Holley fuel pump forum which blames a loud in tank fuel pump on pump cavitation. I don’t think that’s the case with my pump as I have a new 100 micron sock on the fuel pump, all new fuel lines and a new 10 micron filter before the throttle body. Fuel pressure is rock solid at 58 PSI and I have no performance issues. I did drop the tank and pulled the pump to inspect the sock and overall pump installation, which all looks good.
Any of you fuel injection guys experienced this issue and if so, whats the fix?
