98 T4R Plugs, Wires and Fuel Filter

How hard or easy would it be to change the plugs, wires and fuel filter if I were to do it myself? I'm not much of mechanic but I do like to get my hads dirty.

I don't have much mechanical knowledge and I managed to change my fuel filter like it was nothing, but you will get your hands dirty and soaked in gasoline .


Couple of tips on the fuel filter that I picked up:

Be sure to depressurize your fuel system. There are a couple of ways to do this, one much easier than the other. All you have to do is unscrew your gas cap, or if you want to get crazy you unplug your fuel filter relay (EFI I think it's labeled), and run the truck until it dies. I did the first one no problem.

Also make sure you put a bucket under it because it WILL leak gasoline for quite a while. There are two bolts that hold the filter to the underbody of the truck, and another bolt that holds the filter to the mount. Of course there is also an inlet and an outlet on the fuel lines, but those are easy. Be sure the bolts on the lines are tight or it will spray when you start it if they are loose, so be sure you look under the truck after you start it before calling it a job done.

For changing the plugs and wires, I have no idea how easy or difficult this is... A lot of Japanese engines make it difficult. But if you can change the plugs, you can change the wires .

Good luck

Well, after two weekends, four tee shirts and two twelve packs, I'm finally done. The spark plugs and wires were a sinch but the fuel filter was a little more challenging. Once I figured out how to depressurise (with your help) the fuel lines, I removed the old filter and bracket and insatlled the new one. That was simple.........the problem I had was leakage. I cound't stop the fittings from leaking gas. After about four different tries I finally put some teflon tape on the fitings which seemed to do the trick. I just hope this isn't a temporary fix and the leak persists. We'll see.

Thanks for the help!

did you buy a toyota fuel filter or a aftermarket filter. I had a problem with purolater filters oem for me.

If the fitting was on correctly, you shouldn't need teflon tape on the threads (those fittings don't seal at the threads... they seal at the tapered end of the fitting.) When you put the new filter back on, did you totally tighten one fitting then install the other? The best way to do it is to start both fittings and start the bolts that hold the filter bracket to the truck before tightening anything down. Then slightly tighten each fitting and bolt alternately until all are tight. This will ensure that everything goes in straight and you should have no leaks when you're done.

That being said, if you have no leaks now, you may be OK with leaving it like it is, but keep this in mind for next time.
