Thomas Group Ltd

Thomas Group Ltd, are specialists in diesel fuel injection, fuel filtration and fuel quality.

Our primary aim is to supply first class products to our customers, with excellent customer service.

About us

Thomas’s are based in Ashford, Kent and have been in the fuel injection business for over forty years. In that time the company has partnered with all the major diesel manufacturers. Beginning with Bosch in 1977, and adding Lucas, Delphi, Denso, Stanadyne, Siemens VDO, Parker Racor, Diesel Forward, Fuel Manager and Hopkins Manufacturing along the way.

Experience, training and a good knowledge of the latest technology is vital in this industry. From our repair workshops to our parts distribution centre we have that in abundance.

Since the company’s early beginnings, technology and emission standards have been revolutionised, from the smoky seventies to today’s tight legislation. This revolution is not yet over, with ever more efficient engines and systems. This makes your fuel system the sophisticated and expensive heartbeat of your engine.
Fuel quality is more important than ever. Modern electronic, high pressure fuel systems must have clean fuel that complies to ISO standards. That means buying good quality fuel and filtration systems. Good fuel will extend the life of your engine and fuel system.

Our ethos is quality. Genuine OE (original equipment) parts, manufacturer training, official tools and software combined with first class customer service. Gaining customer feedback to help us constantly Improve is our continual aim. If you need technical support with a part, we will try to give you the information you need.
Our markets are anywhere you can find fuel injection. That could be construction, marine, agriculture, power generation, rail, cars, trucks and buses.

Our customers are worldwide. With our varied shipping and payment options we try to make buying from us as easy as possible. An on-line trade account will give you access to thousands of products. We will also try to find rare and obsolete parts through our network of contacts.
