Found these in diesel fuel TANK

What are these light brown very soft pieces that were in my JD loader fuel tank and also in that big JD plastic-glass filter. Bought this loader this late winter so do not know a history of what has been put in the tank. They feel just like grease from a grease gun. They will dissolve in gas in just a few minutes. Trying to post a pic...

Maybe the bacteria that can live in diesel once it gets a little water? I bought some biocide this summer to prevent that.

wax or paraffin balls that form in diesel fuel base at about 26 degrees? A bit of moisture and algae added then stays as soft ball at warmer temps, gets blocked by good filters. Disolves in gas?- standard for many cold weather diesel is the addition of 10% unleaded gasoline to diesel fuel for use in cold- Bosch pump lubed by engine oil recommendation but not for GM distributive lubed pumps goes up to 20% because it lowers 'wax' point much lower by keeping 'wax' from forming. Summer fuel oil, heavy diesel fuel, railroad grade high sulfur diesel fuels sometime available cheap for off road use and 'diesel tractor fuel' at reduced price may have 'heavy' fractions from refinery in it that form 'wax' balls at lower temperature while road taxed fuels that are winterized won't. 'Heavy' diesel isn't a bad thing, has more energy/BTUs per liter than 'light' fuels which can mean a bit more power or a bit better economy when running during summer. You don't know previous fueling history so maybe previous owner used some heavy furnace oil because it was cheaper and seemed to help pull better in summer--and old JD 2 cylinder diesel engines were designed in the high sulfur thick fuel days so some people may think Green Tractors need heavy diesel. Mild Teasing Alert! here. RN.

Looks like something left behind from the cat!

Looks like chicken livers . Lets go fishin

Werther's originals?

RN has your objects identified. Paraffin balls or wax balls. In years past when we did not have as good of fuel treatments you would find them fairly regular in diesel fuel tanks.

shrimp

rubber bands !!!!back in the day of the MF 2000 tractors we found a lot of them in the fuel tanks and fuel lines on them tractors. at that time MF was having union trouble and the workers were dropping and putting them in the tractors. after time they swell up and caused all kinds of problems. pull many out of fuel systems on the 2000 models made in Canton Ohio

Have also found residue like that in several machines...All after running alot of power service and desiel fuel additive thru the winter....Just educated guess...CH

RN thanks for the good information--very useful and helpful......

Russ---what is the name of the BIOCIDE you bought.................
