Fuel Tank Rust Removal

MotoCaribe always strives to offer well-maintained bikes for our guests, and spend a lot of time, effort and money to do it. Anyone who has toured with us know our dedication to maintenance.

I have one bike in our fleet that has been a problem child through no fault of it's own, kinda pilot induced. I usually ride it because of it's history. This time is was a clogged fuel pump filter because of a lot of rust in the fuel tank.

This particular bike had been crashed some time ago and sent to the dealer in Santo Domingo for extensive repairs we didn't want to do ourselves at Camp Moto. The tank had been emptied and left open in their shop for 3 months, and the Caribbean salt air did a real number on it unbeknownst to us. The main rust was in areas we couldn't see. We didn't know we had a problem until some appeared in the fuel filler neck and the bike developed a clogged fuel pump filter.

We looked at options to remove the rust with the pluses and minuses. Vinegar, sheet rock nails, muriatic acid, all manner of store-bought systems, you name it. For numerous reasons, the primary being cost and the science behind it, we chose electrolysis.

Although we've never done anything like this, the process was simple, effective and very cost effective. We had all the materials necessary at Camp Moto. I will say that pressure cleaning the tank after the rust was removed was a huge help.

Here is a video of our experience:

I have used the battery charger, washing soda (electrolyte) and sacrificial anode method with good success. It does unfortunately take a lot of time to work. The last few tanks I have cleaned I used milkstone remover mikes a 5:1 water/milkstone remover and in 24 hours the interior of the tank is clean as a whistle. Rinse out with hot water and swish a bottle of high proof rubbing alcohol around to help dry up any water and your done.

I took the fuel pump apart to replace the fuel strainer and this is what it looked like:



Additionally, under the strainer was a pile of red muck that washed off. Curious as to what further damage the fine rusty muck could cause---too fine to be trapped by the fuel strainer---I took the top of the pump assembly off---where the fine strainer/filter lives---disassembled it, washed thoroughly with gas treatment and blew it out with compressed air in both directions. An amazing amount of fine gunk came out, obviously stuck in the high-pressure side. Cleaned & blew it until clear.

Reassembled, put the tank back on and bingo! Bike runs perfectly.

As I understand it, both milkstone & vinegar, while effective, result in rapid flash rusting left unattended for even a short time.

I---or my sources---could be wrong.

That's another reason I chose electrolysis. I've read no incidents of rapid flash rust, and no need for further treatment.

Any unprotected steel no matter what method was used to remove the rust will flash rust.

Once a tank is clean and dry if it does not leak I do nothing further but try and keep the fuel level topped up. A bit of flask rust is nothing to worry about.

Awesome, great video! I tried the cider vinegar treatment to my old Honda tank, which appeared to be working, but I think I left it too long since by the time I got around to emptying it out the tank had rusted again.

The electrolysis process seems a little better for an overnight treatment, and I'm sure it smells a lot better than the vinegar too!

I'll give it a shot before spring and I'll try and remember to post my results when I'm done

look forward to video when I have free wifi. Replacing that filter was spot on. Great info.

I'd suggest at least two days for the electrolysis to work depending on how bad the rust is. If I had to do it over, I'd have dumped the liquid out after two days, refill with fresh, and done electrolysis for an additional day.

Pressure cleaning is also an important factor. The V-Strom tank is problematic because of the shape and fuel overflow tubing.
