/ Hi there and welcome to JA. The first thing that you will need to do is remove the fuel lines and shutoff wire off the fuel pump then you will need to remove the four bolts and on the bottom two bolts there will be a support brace that holds the air compressor. after you remove the fuel pump you will need to drain the engine coolant. then you will need to disconnect the air lines and govenor. Also you will need to disconnect the oil pressure line. after you do all this then remove the four mount bolts. To do this job you will need a twelve point half moon wrench sizes 9/16,5/8 to get at the bottom bolts on side of the engine block. Hope this helps
