My 715B tank was cleaned 2 years back using vinegar and looked good but now problem back with rust clogging the small pickup port . Solid but rust is a problem as can't keep tank full all the time and it seems the mix of bio-diesel added to fuel now promotes moisture and rust . Local place says they can coat tank but when asked on price - quoted $450 and 2 year warranty . Wondering on what coating holds up to diesel . Few years back I bought a treatment for motorcycle tanks but have not used it . See several coating advertised and like most things they require a warm area to fully process and cure products . So might be a summer job when temp stays above 70F out Will clean tank with Inhibited HCL acid to prep then and go from there . Might also add a larger outlet to tank and a pre filter screen in case of debris in tank . Odd have had machine now for 30 years and only last 2 years has this become a problem . Wish there was a way to just plate the inside of the tank with zinc or copper but guess a coating is the way - if it stands up to the fuel . ------------- Faith isn't a jump in the dark.

Likely an EPA reformulation of the fuel has changed how it reacts with the metal of the tank... ------------- Source: Babylon Bee. Sponsored by BRAWNDO, its got what you need! |

I cleaned my tank by strapping it to a cement mixer, letting it turn over and over with stainless pins and stainless nuts of random sizes. I removed a bunch of crud but I did not coat the inside. After I reinstalled and was running, I stopped in Napa for a part and next to the counter was a cart with fuel tank coating. Could have been a sign but I missed it. |

Cleaning it is easy part , keeping it clean after is the hard thing Need something to line the bare metal to keep the rust from reforming . ------------- Faith isn't a jump in the dark.

Coke: Was sorting through Mil Specs. on this subject and came across this - https://www.scribd.com/doc/89939485/MIL-C-4556E " rel="nofollow - https://www.scribd.com/doc/89939485/MIL-C-4556E ; probably no longer used as there is a mention of lead chromate. Wondering if there was an update that would be useful to protect the interior of diesel fuel tanks? Orangeman

Just think about the nightmare you will have when that coating turns to glue and get all through your fuel system. I've had that happen with a few professionally done gas tanks and would not even consider doing a diesel tank. I found a place locally that will solder coat a fuel tank. This works great for eliminating re-occurring rust. For a fuel tank that is square or rectangle hidden behind sheet metal it could be more cost effective to have an aluminum tank made, than the cost of cleaning and coating. ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits. If you can't make it GO... make it SHINY |
