Has anyone ever changed their own inline gas filter on a W22 chassis? Some say, you need a special tool to remove the filter and some say there is pressure in the line and gas will spray out. Any ideas????

RANGER REG: YOU can make it a lot easier for our members to help you if you will please add some rig specfic info to your signature (go to profile). The reason that is important is because there IS a difference in fuel filters on the W-22 depending on model year.

To answer your question as best I can:

IF your filter is mounted inside the frame rail, just behind the left (driver's side)rear axle, you only need two open end wrenchs. One to hold, and one to turn. There may be a small gas drip initially, but it is not likely to spray all over if you crack open the connection slowly. Just loosen both ends, remove old, install new, and crank engine to test for leaks.

If you have a newer chassis with the new filter with two fittings on the OUTLET side, I have no experience, but have read it is quite expensive and harder to find. Good luck, ED

Reg, your 2002 W-22 will have the older filter, just follow ED's instructions you should have no problem an welcome to irv2.

You may need a flare nut wrench if the fittings are really tight. An open end may round them off. As to gas spraying out - it will dribble a bit at first but it won't spray uncontrollably all over the place. After you crack the fitting loose, keep some paper towels wadded up in the frame rail to catch the drizzle and be sure your body is slighty off to one side, not underneath the filter, and you'll be fine.

Thanks for the info. Yes, I have a 2002 chassie and I may just try to do the job myself. I feel I can save some money doing my own maintenance. I was going to change the tranny fluid to synthetic but decided to let Allison's service dept do that job.

Reg...an old mechanic's trick is to tie a rag around both wrists when working on fuel lines under a vehicle and wear safety glasses. If the fuel drips, it's absorbed by the rags.

P.S. I'm a fire investigator and responded to a car fire where the victim was changing his filter (under the vehicle) with a trouble light beside him. Fuel dripped on the hot bulb and ignited. He died from his injuries several days later...be careful!
