Replacing fuel pump on 69 340

I dont remove the Alt' completely but I do remove the lower bolt and rotate it up and out of arms way.
The lever on the pump has a fairly strong spring. If the ecentric is to the high side you will fight harder against the spring. If the ecentric is to the low side you still have a little resistance but much less likely to cross thread the pump mounting bolts.
The Airtech pumps from part stores are junk. Buy a Carter OEM replacement from RockAuto.com. Few more coins well spent.
