Im having trouble with my Holley Dominator fuel pump. Im fighting inconsistent pressures. At a idle the press will bounce from 6 to 8 lbs. With engine off the press will go over 12lbs in about 5 sec. Im using a Holley press reg # 12-704. I have 2 #8 lines supplying the pump #12 line out of the pump to the reg #6 return line from the pump to the tank and 2 # 8 lines to the carb. We just switched to this system this week. Fuel volume was a issue today the screens in the inlet of the pump were plugged. I cleaned them earlier this week with carb clean and they appeared to be clean. But after getting home i dissasembled the pump and i couldnt blow through them. The screens still appeared clean, I temporally removed the screens and that solved the volume problem but the press issue is still present. Anybody have any ideas? It looks like Holley discontinued this pump were they having problems with them? Thanks Seth
