Begin by loosening the large bolt on the top of the filter housing. There are two styles. This one is a later style, that has a 24mm bolt. An earlier style uses a 22mm bolt. You'll need to verify yours before beginning.
-
Once the bolt begins to loosen, you'll need to use your other hand to hold the filter.

-
Inspect the bolt. On the newer style, as pictured, there are two different sizes of o-rings to seal the bolt. One the earlier style, there is only one o-ring.
-
On this bolt, the o-rings are old, brittle, and flattened. They need to be replaced, there are o-rings in most metric o-ring kits that will fit.
-
On the early style housing there is also a copper crush washer that goes under the head of the bolt, in place of the second o-ring. This should be replaced with every filter change.

See the new o-rings installed here.

Fill the new filter with fuel. Diesel, or anything else that will burn safely in a diesel engine, such as virgin motor oil, virgin vegetable oil, clean automatic transmission fluid, or some diesel purge.
-
Doing this will reduce the amount of fuel system priming that is necessary.

Prime the system using the primer pump until the fuel pressure release valve opens. You'll be able to tell by the squeaking noise from the injection pump.
-
Now is also a good time to replace the clear plastic primary fuel filter. If you'd like to do this, and need guidance, see the primary fuel filter replacement guide.

Using Two people One can operate the starter while the other operates the hand pump until the engine begins to run---then close off the hand pump and starter switch. gary
This is a very clean and concise manual. Nice Work!
To gvonneida and the general public
You could do that but it would be unnecessary as this a gravity fed injection pump, and there isn't any low pressure/lift fuel pump. So there is nothing gained from the 2nd person/engine cranking. Just use the hand pump to prime the high pressure injection pump, the engine will start no problem.
Dirk, just to correct something, there is a low pressure lift pump on these engines. That is what the primer pump is sitting on top of. However, you are correct that generally it is unnecessary to crank the engine to help with starting after you replace the fuel filters especially if you pre-fill the secondary large filter. Just use the pump until you hear the bypass opening (the squirting/wooshing type sound) and you know your fuel system is full of fuel.
Do you mean that you can install the secondary filter dry and pump the primer to fill it up?
Hiya! I’m about to change both the primary and secondary fuel filter on my 300D and was curious if it would be a problem to use the priming pump to fill up the secondary filter. Thanks for this guide!
