Hey all just wondered if it is normal for a carter mechanical fuel pump to drop down to 5-1/2 pounds pressure when it gets warm? When I first start the motor it runs at about 7 pounds and after it warms up it drops down to 5 to 5-1/2 to 6 it kind of bounces back and fourth around those pressures and sometimes lower. Is this normal? I have a 3/8 fuel line along with a 3/8 pick up. I had a holley pump that would start out at 8 pounds and would drop down like that when it got warm also. just curious if this is normal
