Looking at Ernie's thread it became clear this needs to be done. I decided to replace hoses and what not as well since the old ones are likely brittle. I ran the car down low on fuel and I am betting I can tip one side way up and do them 1 side at a time. we'll see. May wait for slightly warmer weather. If anyone needs it, here is the parts list I used with the newer 53mm Bosch fuel pumps from Rock Auto. You have to order the right rubber boot/gasket for that size, the pumps are 2 sizes the older 60 mm and 53mm.
