Are you talking about the pick up? IF SO...... I would always put my pick up on the pump with it hanging really low past where the oil pan would be...then I would set the pan on so it pushes the pickup back up..carefully remove the pan and push the pickup 1/4 closer to the motor to give a little clearance.....Mark it and stick a tack weld on it....

Does that make sense???

That is the only pump I would run... I never did use the white spring though and my motor always had great oil pressure..
