Experienced Professionals:

As President of Double R Diesel I feel it is important, to our customers, to state our dedication and experience in the diesel engine business.   I started working for Diesel Services Inc. in 1996 in the fuel injection shop. During my time with Diesel Services I performed many jobs, fuel injection tech, fuel injection shop service manager, industrial engine tech, industrial engine service manager and many others.  In May of 2017,  I was able to take over the fuel injection side of Diesel Services Inc. and start Double R Diesel Inc.   Your diesel engine deserves the best professional technicians possible.

At Double R Diesel, we will continue to offer the same level of service you have come to expect from our 21 years of experience!

Most issues with gasoline injectors are sticking valves caused by sitting for extended periods. We see this a lot with marine engines or we can test the injectors as received, run them through the ultra-sonic cleaner while the injectors are pulsed. This breaks down the debris and junk around the valve. After cleaning, the injectors are retested to confirm they are functioning properly.
