I put a new Holley mech. pump on and turn the motor over and I don't feel any air moving when I plug the holes with my fingers. And the plunger arm on the pump is 1/8 shorter than my old one. Should I be able to feel anything when plugging the holes with this particular pump, or will it pump fine once I get gas to it or do I need to get a longer plunger? This is suppose to be a stock replacement pump only better. Summit part # HLY-12-327-11. I'm also using stainless braided fuel line to my carb and was wondering what would be a good fuel filter with -AN fittings. Thanks.
