Fuel Filters, part 1
This is the engine filter replacement. The chassis filter replacement is in the next one I post.
The engine and chassis fuel filters are nothing to be afraid of. I drug my ass and it only took me a half hour from beginning to leak check. (Especially since the stealer wanted $300 to change them.)
Disclaimer: I did not disconnect the battery, even though the instructions said to, and I did not drain the chassis water separator bowl, even though the instructions said to. You be the judge of how you perform this task.
The engine mounted filter bowl is right in front of the air intake snorkel. Use a 1-1/8 in. six point socket to remove this cap. DO NOT ATTEMPT THIS WITH AN OPEN ENDED WRENCH. You will jack up the lands on this composite cap and end up buying another one. Same warning for the chassis filter bowl.
Pull the cap off the filter; it will likely stay behind on the spiral pickup tube. The bowl will not spill as it drains as soon as the cap comes off. Once the cap is off, pull the filter element upwards off the pickup feed. Take the new filter element, lube the inner filter gasket and press it down on the spiral feed. Then take the cap, discard the o-ring, take a little diesel and lubricate the new o-ring, and seat it in the groove on the cap. Spin the cap down hand tight, then use the socket and a torque wrench to seat the cap to the required torque. Time on job: 7 minutes.
