Has anyone else noticed that Holly's "new and improved" 110gph fuel pump-hly12-289-11- not only uses a new diaphram design but also different shaped pump arm? Assuming they knew what they were doing,I installed it in my 351W. NO FUEL PRESSURE
The cam eccentric just barely marked the edge of the arm. I took it to P.A.W. and compared it to a new Edelbrock pump. The Edel had the same design and arm as my old Holly pump and works fine, so I will send the Holly back to Summit. Is it me or did Holly get taken over by morons?
