I have changed one out on a 318 and a 360. I remember two bolts holding it on and the fuel lines. If the coil is in the way, it is not a big deal to remove that to gain access. I would disconnect the battery prior to begining. On the new one, put some motor oil on the portion of the lever which rubs on the cam lobe. There will be some tension felt when you properly position the new pump to contact the cam prior to installing the mounting bolts. If it was leaking, do an oil/ filter change as some gas likely got mixed with the oil.
