Caterpillar 3208 Solutions This sub-forum is hosted by Mike Hohnstein who has been at this kind of thing for 50+ years now, guess I'm addicted. The saga has been all about progressively larger shop space since then. Honestly, never wanted to get into the CAT 3208's that were originally considered to be a throwaway engine but that's all that works in a FC in my world. Same thing with my Ford toter, that came with a NA, too much effort to hang in a 6, so been at it with the CAT V-8 for 20 years now. In reality you can get excellent life out of a CAT 3208 if it's built correctly. Post your questions about the CAT 3208 engines here and Mike will try to help you out.

Default Losing power (water in fuel)

First off it seems my Racor has been replaced with a fs1212 water separation filter. I am losing power up hills bad and max ful flow light staying on. I pulled over for the night and drained the fs1212. It had about 30 ounces of dirty water. My tank is about 1/4 full and has been that way in some cold weather over the last few months. Question is what should I do in the tank and should I g ahead and replace both filters. We have a 800 mile trip. Thanks.

I would replace the filters. I would also go buy several more right away! Especially the one catching the water. Next time, I would just replace the water separator one. I do not know if there is a drain on the bottom of the tank. The experts will chip in on that.

Otherwise, I would keep replacing the water separator, until it gets most of the water out. Then, and only then, I would use a water dispersal agent in the fuel. If there is a drain you can use, do that, then dispersal agent.

If you can find a service that will "polish" your fuel, I would highly suggest using that. They can clean all the water, and junk, out of your fuel.

I went thru a big whoop dee doo in TX last year. 50 miles later, I was losing power, and needed to change the filters. I am sure that big dip sloshed fuel around, and stirred up junk off the bottom, 25 years of settling there. If I find a polisher when I am traveling, I am going to have it done, and try to get some of that out. Not sure if they can stir it up off the bottom though.

Sure sounds like a fuel/ fuel flow issue. However, its probably a good idea to rule out linkage /throttle cable problem. If your not getting full rpms with accelerator mashed, then open dog house and pull back on throttle from there. This will rule out or not accelerator cable / linkage fail which would also produce low power symptoms.

Don't ask me how I learned this

Good luck.

Hi John,

Nice to see you back! Haven't heard much since seeing you and the kidlets at WOG two years ago.... I'm pretty sure you have a drain box on the bottom of your fuel tank. Get one of those 8-quart, round, oil change tubs at WalMart and screw the bung-plug out of the tank or open the petcock (not sure which you have). Drain a gallon of fuel and most of the water should come out with it. I do this annually when I change the oil. You'll get rusty water, pieces of rust and sludge normally.

Thanks Mr Fedeli
I never thought of draining the water out of the tank for regular maintenance . Makes wonderful sense .

Just remember to keep your mouth closed and wear glasses. It makes a pretty good splash!

If it is just a plug, and not a drain valve,, I would try to get the fuel level pretty low. Otherwise, there is a lot of pressure and fuel coming out, while you are trying to get a plug started! Don't even THINK of asking!

If you are sucking water you are probably pretty low on actual fuel to begin with. I would go ahead and drain the tank but first have everything you could possibly need if things go wrong. Because if you don't Murphy will be in charge. Don't forget the jack stands. Good luck.

fuel will burn your arm if you don't wash it off good.
this job you cannot pay to get done.
everyone is not WL owners and don't care for these units like we do.
but once you do this its easy the rest of the time to get the stuff out
