About Us:  Conestoga Diesel Injection is hard working people.
Conestoga Diesel Injection was founded in 1986 by Glenn Ament.  He started the business in a garage owned by his father, using up one of the bays.  As Glenn's business grew, he took over more of his father's garage until eventually he had the whole building.  Glenn retired In the fall of 2012, when he sold the business to Mel and Suzi Agne. 


Mel is an experienced diesel mechanic and technician with decades of knowledge, specializing in Ford and International Indirect Injected and HEUI engines.  His background also includes a 31 year career in information technology, electronics, machining and diagnostics, giving him an excellent skill set so important with today's computerized engines.  He has also performed maintenance on diesel locomotives, cranes, and a variety of specialized equipment.  Mel spends countless hours devoted to serving our customers, and does the lions share of helping people on the phone with vehicle and performance questions.  If you call, there is a good chance you will speak with him.  Mel says  "We get a lot of the problems other shops have had difficulty solving.  I like a challenge, and enjoy solving complex and difficult electronic and electrical issues." 

Suzi Started her business career in office administration for various firms.  She also was a certified school teacher specializing in early childhood education, a cook, and is now our Office Manager.  Suzi wears many hats at Conestoga Diesel Injection, and does reception, accounts payable, accounts receivable, inventory, parts, and many other tasks.  She even builds our injection return line kits!
