I was asked to describe the process for changing the fuel filter on our Davco fuel processors.

1. Loosen top plug
   
2. Drain the filter glass down to at least 1" BELOW the ring.  This is so when you remove the ring & filter glass there will be no spillage. 
   
3. Remove filter ring & remove filter glass.  DO NOT remove the filter yet.
   
4. Drain the diesel down to the bottom level of the Davco where the filter sits.  If you don't you will overflow as fuel will drain from the filter when you remove it.
   
5. Now remove filter & dispose.  Make sure bottom rubber grommet came off with the filter.  If not remove from Davco.
   
6. Install new filter
   
7. Install new o rings on glass ring & top plug.
   
8. Clean & replace glass cover.  HAND TIGHT only on the glass ring.
   
9. Fill fuel through top opening until the filter is totally covered.
   
10. Replace top plug & tighten, hand tight.
    
11. Start engine and run on high idle for 2-3 minutes.
    
12. Take off high idle, but keep engine idling on low.
    
13. Slowly open top plug until fuel level begins dropping.  Allow fuel to drop to about 1/2" above glass ring.  Tighten top plug--Hand tight only.
    
14. You are done!

I would like to offer an alternative for step 9.

In the event you would rather use the fuel you no doubt have in your tank, rather than what may or may not be available in a container when you need to do the filter changer - consider this.

Located next to the fuel fill is a black knob. If you turn this knob counter-clockwise it will pop out. Now it's a pump and just pump until the fuel from the tank is moved into the filter. At least that's how it works for my '99 vintage Series 60.

Thanks for that input. I have tried to use that pump, but could not move it(I thought it was frozen up from lack of use) did not know to turn it counter clockwise
