My 7.3 Diesel

[Bduck]

On the front of my engine is the HPOP. There
is an access service port as I point to it.



I have a pump that is operated using a drill. The small tubing
inserts into access point pushing it to the bottom of the 
reservoir and draws oil out.



Warming engine naturally help oil to be extracted. This oil
definitely has been in this system for a lot of miles.



I stole the turkey baster from the kitchen and removed
the rounded lip to fit into service port. I serviced, ran engine for 10min
& extracted the oil out repeating process 3 times. I can't get the oil from injector 
delivery replaced unless I service the reservoir and running motor.




Next is the fuel filter. This is the filter housing looking down
at the fuel heater mounted on bracket with 2 hex screws
holding in place. Coming up thru center is a stem that goes
up thru filter. 



When removing fuel heater, the filter stem come out. Easy Peasy



On the bottom of stem is a spring with a plunger above it inside
stem.
 



I removed plunger & spring reinserting stem as this is
the guide for the filter installs. The spring & plungers' purpose
is to prevent engine from running when filter is not installed. With 
those items removed; it eliminates fuel restriction. There will
be a filter at all times installed.
The only thing I can think of is why the shop doesn't mention this service
is potential for a future $5G for injector service. When I got my truck 
out of shop from an oil change last week, they recommended a 60G service.
