The inline filter on the fuel injected models is found along the frame rail.

Properly relieve the fuel system pressure.

CAUTION
The 220 TBI unit used on the V6 and V8 engines contains a constant bleed feature in the pressure regulator that relieves pressure any time the engine is turned off. Therefore, no special relief procedure is required, however, a small amount of fuel may be released when the fuel line is disconnected. To reduce the chance of personal injury, cover the fuel line with cloth to collect the fuel and then place the cloth in an approved container.

Disconnect the fuel lines.
Remove the fuel filter from the retainer or mounting bolt.

To install:

Install the filter and tighten the bolt to 12 ft. Lbs. (16 Nm). Connect the fuel lines and tighten the nuts to 20 ft. Lbs. (26 Nm).
Road test the truck and check for any leaks.

The filter has an arrow (fuel flow direction) on the side of the case, be sure to install it correctly in the system, the with arrow facing away from the fuel tank

If the filter has threaded fittings on both ends, all you need is a couple of wrenches. Make sure there is no pressure on the fuel system, before taking any lines loose. After the vehicle sits overnight without the key being cycled, there shouldn't be much pressure. You still need to be aware of possible pressure.
