The pump is too big or the regulaor is too small. You pick. The pressure is
probaly greater than 8 lbs. as well the 1 dollar gauge that comes with most
regulators is worth something less han the 1 dollar the oem paid for it.
there is no way a good regulator can have a range of 3 lbs to 60 either
without changing springs and orifice sizes. What do you have for a pump?.
Most holley needle and seats will hold 7 to 8 psi all day or there would be
a lot of drag race cars on fire.
