70 Chevelle, 489 BB, Jerico DR4
So I finally hooked up a fuel pressure gauge and measured 8.5 psi and automatically thought this was too high. Everything I've read says 7 psi max but back in the day many TC'ers ran this pump just fine without a regulator. So I pulled up a spec sheet and it's an 8.5 psi pump. Also the comparable Holley pump is rated at 8psi. So what gives? I'm assuming as long as the needle and seat is not overpowered and you can set floats it's all good?
