I need to replace oil pump on a 1988 ford bronco 2

Remove oil pan, making sure to drain oil first. Remove oil pump attaching bolts. Lift off oil pump and withdraw oil pump drive shaft.
INSTALLATION;
Prime the new oil pump by filling either the inlet or outlet port with engine oil. Rotate the pump shaft to distribute oil within the pump body. Insert oil pump drive shaft into block dwith the pointed end facing inward. The pointed end is closest to the pressed-on flange. Place oil pump into position with a new gasket and install attaching screws. Tighten the screws to 15-22 foot pounds of tourque. Clean and install the oil pump inlet tube and screen assembly with a new gasket. Tighten the bolts, then replace the oil pan.
Oil Pan;
Clean of any debris and replace gasket. Fit the oil pan bolts and tighten in two steps. Start from the rear/left hand side and tighten first, then tighten the bolt in the front/right side. Alternate from rear to front, working from back to front and front to back.
