04 fuel filter?

[DocDetonancour]

For you guys with the new HO, how hard to get to the F. F. and is it a cannister or spin off? Thanks, Doc

Fuel filter is easy to get at. It's in a canister... you just replace the element inside. Just have to be careful not to get any dirt in the fuel system.

1. Drain the fuel.

2. Remove top from canister with a 1 1/8" wrench. Don't use the square drive hole, you will crack the top.

3. Remove old filter and discard the old O ring.

4. Wipe out canister with clean lint free rag or towel.

5. Put in new filter.

6. Put oil or diesel fuel on the new O ring and replace top of canister. It will turn a bit hard because of the seal. I just get mine "snug". Do not prime the canister.

7. At this point, make sure the drain is closed.

8. Turn key to "start" but just hit it without starting vehicle.

You will hear the fuel pumping into the cannister for about 22

seconds. I do this a second time, I don't know that it is

necessary.

9. Start truck and let run for a minute or so, check for leaks around cylinder and you are done. Pretty simple.





This is a very simple operation, just be aware that the top turns hard at first and when tightening up because of the o ring and the prime with the start function. Good luck .

Why would you drain the fuel ?

From the cannister. Why wouldn't you .

I just changed mine. I didn't see the need to drain it. The

only fuel that toughed the engine was when I pulled out the filter. I was just curious or there was a specific reason.

Service manual says you must completely drain the fuel filter housing prior to removal of the fuel filter.

You want to drain the fuel because if you don't, some of the dirt may run off your old filter and contaminate the fuel you left in there. Now this dirty stuff is on both sides of the new filter and will happily migrate to the high pressure pump and injectors down stream.

Water?

Besides the fact that it's a canister filter, contamination to new filter as noted above, to remove any water traped in the bottom of the filter housing. Pretty good reasons in my book.
