Sooner or later for various reasons ,mainly contaminated fuel, we have to replace the fuel filter on the side of the road. Most of the F250 owners are familiar with this but if you are not I'll describe it and put some pics in my album for future reference.

The filter/water separator is located on top the engine just behind the plastic cowl that says Powerstroke. The cap is black and is about 120mm across.

Before opening you have to drain fuel from filter housing, this is done via the drain valve and pipe that comes out of the rear of the filter housing at about 11 o clock looking from above. The valve handle is yellow and points to the RHS mudguard in the closed position and the rear of the truck in the open position. (see pics)

The pipe leading from this valve goes down the RHS front of the eng block and ends just above harmonic balancer height and drops the diesel to the ground. I place some plastic tube to extend this pipe into a clean container to catch diesel as it drains filter. (see pics)

Turn handle to open position and let fuel drain out (approx 500ml). This is the way you drain filter if your WATER IN FUEL light ever comes on .... Now you can remove filter cap (turn anti-clockwise) and filter pulls straight up to remove.
Clean rim of filter housing where "o" ring sits with lint free rag and " just " wet o-ring on new filter with diesel.

Depending on type of new filter place filter in housing and screw cap on or if other type
(filter and cap in one) place in housing and screw down.
Torque wrench setting is between 10 and 15 ft lbs ... I tightened mine to 13. If you dont have a torque wrench, after cap "just" seats tighten 1/4 of a turn .... dont overtighten.

Close drain valve ... remove hose from pipe .... turn ignition on til pump stops filling housing (for at least 1 minute) then fire up and check for leaks at filter cap rim.

If you have trouble getting cap off .... I use two shifters one opened right up and placed in ribs of filter cap and the other on handle of it .... turn anti-clockwise.

I'm checking on filter in pump on chassis ... that will be next instalment.
