He Specializes In “Heritage” Diesel Fuel Injection Repair
“I was born and raised on a farm, and spent a lot of time fixing old tractors and working on cars as a teenager. I gravitated toward fuel injection repair about 20 years ago, opened this shop in 2013, and it has been going gangbusters ever since,” says Ed Guenther of Heritage Diesel, Walnut, Ill.
    Guenther’s speciality is overhauling heritage diesel injector systems built from the early 1960’s to the 1990’s. “Right now I’ve got injectors in here from a Ford 900, an 1850 Oliver, a 1010 crawler, a 220 Allis, an IH 1466, an IH 1256 and a CIH 7150,” Guenther says. “Products that I don’t work on in-house are handled through my various suppliers. I can also build fuel systems for tractor pullers.”
    Guenther says he has puller customers across the U.S. and Canada and also works on his own pulling tractors, though he doesn’t have a lot of time for that.
    “Customers send me injector pumps from their heritage tractors and I completely take them apart. I clean and inspect all the parts, replace what’s necessary, then put them back together and calibrate them. I have 7 different kinds of test stands, so I’m able to handle almost any pump out there.”
    Guenther says many injector system problems are caused by fuel that sets for a year. “The fuel goes sour, just like milk that sits in a refrigerator way past its expiration date. A person wouldn’t drink that old milk, and a diesel injector shouldn’t be subjected to old fuel.
    “There’s a lot of bio diesel on the market today, which is good for the farm economy, but the higher the bio content the worse the problems are because the bio attracts moisture when it sits,” says Guenther. “Then the lines, orifices and internal parts start to gum up, especially if that old tractor is only used occasionally.”
    Guenther advises heritage diesel owners to use fresh fuel and a quality fuel additive to keep the fuel from going sour and drawing moisture. Also, start and run the engine often and use up fuel in the tank before refueling. “That won’t completely prevent problems, but it sure helps,” Guenther adds.
