We have a 2008 GC CRD, I have heard a from a few owners locally that drive one, that they had to replace their fuel tank due to rot.

I crawled underneath the jeep to have a look and see if I can remove the tank skid plate, and clean out the dirt between the skid plate and tank, but is skid plate also holding the tank up? Is there a step by step instruction somewhere on how to remove this?

I just want to be ahead of the game, as I heave heard it is not cheap to replace these fuel tanks , and they are hard to come by.

Our Jeep has 149000km on it, and I've heard that they spring leaks at around 160-180000km .

I just finished up sealing my tank with a POR15 fuel tank repair kit. What a pain in the *** to do on these tanks. The dealership has the balls to charge $2000 for a new tank. Pissed me right off. There were multiple pin holes in the tank when I got all the rust/paint cleaned off.

I only recently completed the job and haven't even filled the tank back up yet, but as far as I can tell, it is a good product and is a viable option...it just takes a lot of time to do. And you'll have silver coating on your hands and arms for days or weeks if you're not extremely careful....there's still some on my fingernail that I can't get off and it's been about a month since I did the job. I figure it must be a damn good coating.

If I were to do it again, or even as a preemptive measure, I would definitely remove the tank, clean up the exterior really well, then put either a coating of bedliner or even a coat of POR rust paint on it. I used some rubberized asphalt undercoating, and I think this was not the right move...it never really cured and I don't know how well it will actually protect the tank in the future.

I did mine with Chassis Saver at the same time I did the entire bottom of my Jeep. I would not want to do this ever again. I do, however, want to do the POR15 inside fuel tank sealer in the near future to make sure I have both sides of mine covered. Mine was not leaking, so I am trying to be proactive on it.
I prepped everything like the POR15 directions, but used Chassis Saver paint instead of POR15. I would recommend someone to make sure they prep well and do an exception job using the POR15 Metal Prep so that the next step really adheres well.

I would think diesel's oily nature would prevent internal rust from forming. I'd be nervous putting any kind of paint inside the tank. Just my opinion.
I really need to drop my tank and be proactive, but i really dont want to do it... Lol

Well I removed the tank, it wasn't leaking yet, but I too I want to be ahead of the game and clean everything before it starts leaking.

As it turns out, the back part of the skid plate was full with dirt, so I cleaned everything off, used a wire brush to clean off the rust and dirt off the tank, and lone behold I see a little pinhole, tilted the tank and what ever fuel was left in there it started too pee out. Wonderful.

Well I guess I have to go and get some of that tank repair goop

I did notice that the back righthand corner of the tank is all pitted.

I am surprised with so many leaking tanks that those jeeps have not been recalled.

Just did this, I waiting until the low fuel light came on, then looked at the miles remaining and waited until that said LOW FUEL LEVEL... had about 2-3 gallons at that point. I couldn't believe the amount of rust in between the skid plate layers. The tank wasn't too bad but did have a fairly rusty spot. I used the undercoating and rust stop. I also changed the foam out for new stuff. I can't believe how expensive these tanks are. What a joke!

damn, I'm not looking forward do doing this job, but it will need to be done.

did you guys install some pad or matting between the tank and skid plate now?

I wonder if there is a way to leave the tank installed but drop the skid plate.
