Quality Diesel Engine Repair From Professional You Can Trust

Backed by a long history of quality and expertise, Thompson Diesel Inc. was founded by Brothers Raymond and James Thompson in 1970, in Oklahoma City. Shortly after, our Tulsa facility opened in 1973, as business continued to boom. In 1992, Raymond Thompson retired, leaving the business to James Thompson, who recently retired in 2011. The current owners of the business are Al Johnston and Everett and Linda Stacy, who have more than 100 years combined experience in the fuel injection and turbocharger business.

Fuel Injection Pumps

The fuel injection pump is an essential part of your car that’s responsible for carrying fuel into the cylinders of your vehicle’s diesel engine. Like with most car parts, choosing the right fuel injection pump is important. In fact, there can be serious emissions-related problems if the fuel flow and pressure aren’t high enough, which can occur as a result of a bad injection pump. The problem is it can be hard to find a fuel injection pump that fits because of the limited selection many manufacturers offer.

At Thompson Diesel, we make sure you’ve got access to the right fuel injection pump to keep your diesel engine running right. We work with top brands including Alliant Power, BorgWarner, Bosch, Delphi, and more. Plus, we can inspect and service your fuel injection pump if you’ve got a problem, so you don’t always have to buy a replacement part. If you’re having problems with your fuel injection pump, give Thompson Diesel a call and we’ll take care of everything.

Fuel Injectors

When it comes to getting the best performance out of your diesel engine, fuel injectors are an important part of the equation. Fuel injectors are responsible for injecting fuel into the manifold, where it mixes with air so it can be combusted. Because of this, fuel injectors are one of the most important parts in terms of engine power. At Thompson Diesel, we can help you get the right fuel injectors whether you’re looking for stock or aftermarket injectors.

Even if you’re not in the market for new fuel injectors, Thompson Diesel can help you get your engine back in tip-top shape. Bring your vehicle to us and we’ll take a look at your fuel injectors to figure out what’s wrong. A lot of times, fuel injectors can be fixed with a simple replacement or rebuild, and we’re happy to help with that.

If you do need new fuel injectors, we’ve got products from some of the biggest names in diesel engines, including Bosch, Delphi, Stanadyne, Ambac, and more. We can even help you figure out which fuel injectors are right for your engine, that way you don’t have to do any guesswork or worry about returning parts that don’t fit.

Fuel Treatments

As important as the parts of your engine are, diesel engine performance is also affected by the quality of the fuel you use. If you want to make sure you’re getting the very best performance out of your diesel engine, fuel treatments from Thompson Diesel can help. We’ve got a great selection of Stanadyne diesel fuel additives that can help increase the performance of your engine. Different additives are designed for different things, so some are great for cold weather while others help your engine start even if the fuel in it has been contaminated by water.

If you haven’t used a fuel treatment before, Thompson Diesel makes it easy for you. All you have to do is let us know what’s going on with your engine and we’ll help you choose the best Stanadyne fuel treatment. We can even show you how to use these fuel additives. If you’re having diesel fuel problems, visit Thompson Diesel and ask about our diesel fuel treatments.

Turbocharger Services

Turbochargers use forced induction to create even more power than a typical diesel engine. If you’re in need of a turbocharger for a diesel engine, Thompson Diesel can hook you up with a turbocharger from one of the best brands. With brands like BorgWarner, Garrett, and Holset, you can rest easy knowing you’re getting a high-quality turbocharger when you choose Thompson Diesel.

We don’t just sell turbochargers at Thompson Diesel. In addition to offering turbochargers for sale, we can help you make calculations to choose a turbocharger and get it installed for you. If you’ve got an older turbocharger that’s not getting the job done anymore, we can take a look at it rebuild it when needed.

When you need a little extra power, a turbocharger from Thompson Diesel is a great solution. With turbochargers from several top brands and years of experience rebuilding turbochargers, you can count on Thompson Diesel to make sure your diesel engine has the power it needs.
