Question
i have a 1989 toyota v6 5 speed 4 wheel drive that i have been trying to change the fuel filter on and one of the factory bolts that are on either end of the factory filter will not break loose from the fuel line. this is a never changed fuel filter. i need advice on possible ways to get this done.

Answer
Bobby,

The first thing to try, is to spray the bolt with a good penetrating oil, and let it sit overnight.  Then try to remove it.  You can use a breaker bar for more leverage, but anytime you have a stuck bolt, there is the chance of breaking it.  If this happens, you may have to drill it and use an easy-out to remove the threaded end, or it may have to be drilled out, and tapped for the next size bolt.  
Remember, WD-40 is not a penetrating oil, but a lubricant.  You can get a good quality penetrating oil at most hardware stores.  Read the labels, and make sure that the instructions specify that it is a true penetrating oil.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you. Certified off-road instructor. I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles.

Experience

40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
