I'm having trouble with a mechanical fuel pump install on a 454. This is a conversion from a POS Holley electric setup. I have a new pump pushrod and pump, but am getting no fuel draw. If I actuate the pump manually it pulls plenty of fuel. Is there a pump spacer plate on a BBC like the SBC that I'm missing? I don't have alot of room to see or work down there, but is it possible for the pump arm to slide to the side of the pushrod during install?
Thanks much!
