Has anyone here changed their own fuel filter on their MKIV before? I'm just curious how hard you thought it was...

I've done many fuel filters on many, many other cars, but I heard that on the MKIV, the flare nut is the biggest bitch in the world and messing it up means replacing the filter-back fuel line (doh!). :urowned:

Am I putting too much thought into this?
Also at what mileage did you change it at?

Any feedback would be great. All these stories are scaring me away from attempting it. If doing it in my garage will lead to downtime for the supra while I wait on an expensive replacement line from the dealer, I'll just take it to a good shop I know of.

Much appreciated.
Jon

make sure you unbolt the fuel filter from the chassis before you try to unscrew the flare nut and you will be fine.

you probably need a valve adjustment :scratch:

Carlo - thanks for the tip!

Tbkonwso - LOL. Why'd you ask that on this thread? haha. It could be a lot of things. An exhaust leak would get more severe w/ RPM increase. Noisy valvetrain should probably be the first thing to suspect.

Importsupyours - thanks. That's encouraging news. What happened to your original reply? lol. Did you delete it?

The fuel filter r/r is pretty straight forward as long as you use a flare wrench and not a regular open end wrench. Be sure to relieve the fuel pressure, and also, raise the front of the car only (this helps to keep the fuel in the tank). Oh, and make sure u have plenty of ventilation and a fire extinguisher handy. :bigthumb:

It's not hard to do. I personally stripped the flare nut beacuse I used a regular wrench. DO not do this! You will strip the flare nut and pay 90.00 for curt to send you a new fuel line. Use Flare Wrenches! if its the original fuel filter be carefull you don't strip the threads, mine had some kinda orange lock-tite on it. Changing out the filter is a no brainer, as long as you're carefull and use the right tools.

Thanks for the additional warnings man. I didn't get a chance to do it yet, but now I'm not all worried...

Those MKIV.com posts made this fuel filter job sound as bad as pulling teeth... :p

it's only bad if you damage the flare, then you can count on spending 2 hours replacing the entire line to the gas tank.

Looks like I'll be replacing the filter-to-tank line as well bro...

I had all the right tools and the flare nut did come out after much struggle. But going all the way into the new fuel filter was impossible. It just wouldn't go in all the way and fuel was able to spray out when the fuel pump was primed. I guess the old flare nut threads just didn't want to work anymore (I read about many cases of this on MKIV.com, which is my original reason for this thread).

So it took you 2 hours to replace the line?
Was it a pain in the ass too?
I didn't get a chance to look, but where is the rear connection at? I'm assuming it's either hiding in the rear suspension somewhere or all the way near the pump. Is it hard to get to?

Yessir I did. I read that it's pretty common for the flare nut to not want to go back in after it was finally removed. Upon removal from the old filter it started ceasing up...never a good sign...

put the car on jack stands and allow all the wheels to have full droop ( espicialy the rear ). Take off the black plastic cover that covers the fuel and brake lines. The hard line goes from filter to just over the IRS. The hardest part is working the old and new line over the suspension. There is a soft line that connects the hard line into the fuel pump assembly. If you grab a flashlight you will plainly see this under the car. Do use anti sieze very sparingly on the flare nut threads so if you ever remove the filter again it comes out with eaze. I ordered the fuel line from Curt Aigner. PM me if you run into any snags.
