What is the best way to clean the fuel tanks on the inside? There is water and sludge accumulated over the years. Water separator filter does its job well, but you can see it at the bottom of the tanks

cost?
Don’t know, I do know that when I was having it done on my old trucks, it was $150 for the cleaning service for the truck. It sounds like a lot but doing it to a 10 year old truck, that was cheap.dorlia2 Thanks this. -

Park your truck on incline that most of sludge is on the side where is fueling cap. Shut the engine off and let it sit for 30 minutes. Take the copper pipe long enough to reach the tank bottom with some plastic hose attached and siphon sludge in the bucket.

Pull all the valves and plugs off the tank and spray the inside of it down in a kiddy pool with brake cleaner to collect any remaining waste a few times to get the last of the diesel amd sludge out then add it to the disposal barrel. Then you just power wash the holy hell out of it a few times and let it dry over a few days.
The hazmat should be cheap to dispose of depending on where you live and who you take it to. Especially if you pour your oil change ontop of it. -

The best thing is to run the tanks low and drain one of them.If you do not have shut off valves on each tank, install them.
Whichever one you drain get a pressure washer or whatever you can and get in there and wash out whatever you can. If you don't have a pressure washer fill up with water and drain it a few times.
Then get a bottle of aluminum bright, you know the cleaner they use for the trailers.Fill up your tank about halfway with water and put the aluminum bright in it and run the truck for 4 or 5 days.
There's no environmental hazard with that you can drain it wherever. Flush it out a few times until the water runs clear. Beyond that your filter will catch it.
Then do the other side and you are all set.
I did it with my tanks because I had bad algae and they were terribly stained. I probably could have left the aluma bright in there longer but it knocked all the crap out of there.dorlia2 Thanks this. -
