Fairly simple,,, remove the drain plug from the side to drain as much fuel as possible,(you can remove the filter and cap also if youd like but its not really necessary), next youll need a fuel line removal tool from any auto parts store. place the tool over the 4 lines and push in while pulling back on the line to release the fittings (this part can test your patience) once all the lines are loose, loosen and remove the three nuts from the outboard side of the frame, that attaches the pump to the frame, now the pump should be loose, just unplug the 3 electrical connections, (2 on the front 1 behind the pump) then it should drop right out, to install reverse the steps, and prime the fuel system by cycling the key a few times. This is an abbreviated description, if I missed anything or anyone has any other input feel free to add.

Thanks for the info. I crawled under earlier and it looks like it wont be to bad. I grew up under the hood so its no sweat, it just helps alot to get info from folks who have experianced it before. Now i feel comfortable with it. I know what you mean about the fuel lines. Thanks again.

No problem SM, just another note, even though you drain the pump and filter housing, you will still have fuel in the lines, no way around it, it wont be under pressure. Its no big deal,other than you will have to explain to your wife why you reek of diesel, for the umpteenth time. lol

How much does a replacement HFCM cost and do you know why this one went out?

Thanks,

Al

The pump was just ordered today because i let a ford guy check it out because he said something about a relay that could cause it. I didnt think it was the relay. I didnt check fuel pressure because i removed the top fuel filter after it died and there was no diesel in it. I dont think i have to replace the HFCM, just the pump that is held in with like 3 or 4 bolts. I dont know the cost yet, it should be in in the morning and ill put it on tomorrow night or saturday.

Just to help clarify, the Horizontal Fuel Conditioning Module : (HFCM) and the fuel pump are one in the same. Its an all in one type of unit. It separates water out, heats, filters, and pumps the fuel up to the engine mounted filter.

Has any one had trouble getting the truck to crank after a new pump install. Could it have air between the filter and the injectors?

Well it turned out to not be the pump at all. I had our shops ford tech check it and it was the ground wire to the FICM. We tightened it up and it fired right up.
