As Hydro mentioned, you can remove all the bed bolts, except the ones nearest the tailgate. Those need to be loosened a lot, but can be left "screwed in" slightly. Then you raise the bed up by the cab and support it on 4x4 blocks. Essentially the bed will be tilted enough to provide adequate work space. Having the cherry picker is certainly handy, but if you don't want to mess with it for whatever reason, then the bed tilt method (with a jack) is fairly easy.

It is my opinion that the pump is a fairly reliable component. That said, failure of the fuel pump at reasonably high mileage is certainly not uncommon. On another forum, TooManyToys has some data on failures (mileage at which some have had failures).

Low fuel pressure can readily ruin expensive injectors. So can air in the fuel. For that reason, it is HIGHLY recommended for every 6.0L owner to install a fuel pressure sensor and gauge. The earlier you see issues, the better chance you have at keeping the injectors. Absolute minimum fuel pressure (at any driving condition) is 45 psig. I use 50 psig as minimum.

I carry a spare fuel pump. Not so much because they fail so often, but because they might and I don't want an early $1500 injector job. You can save some money and buy only the pump. Ford does not sell the pump by itself, but you can buy it separately in the aftermarket. That said, if you have had poor quality fuel, it might just be best to buy the entire HFCM. Crud from bad fuel can plug up things inside the HFCM.

Fuel pump (made by Racor who is the company that supplied the OEM fuel pump):


HFCM pump and Manifold (cover) - part # 6C3Z-9G282-C

Sometimes the pump will pull air in at the water drain plug (it corrodes or the o-ring seal deteriorates). It is best to upgrade the water drain plug with the brass one below (Part # 6E7Z-9C082-A):

The drain plug o-ring (stock and also the updated plug) are most likely Buna N material. Viton holds up much better. The o-ring size is 111 if you want to upgrade to Viton.

The fuel supply is critical to good operation and to the health of EXPENSIVE injectors.

Glad it is running now, but buying a used HFCM from a junk yard is just asking for problems IMO. Who knows how long the seals in it will last - or even the pump.

In addition, low fuel pressure will kill injectors. Failed injectors could damage the engine.

I have serious doubts that your current approach to fixing the 6.0L will give you long-term success.

You still don't know what risk you have incurred until you check fuel pressure............. And even then, the failure rate of a junkyard pump has to be higher than that of a new pump - making a fuel pressure gauge even more important. The 6.0L will run fine on fuel pressure that is pretty low - right up until an injector fails.
