2019 F-250 came in for a DCR pump conversion along with a few preventive upgrades to help keep this truck reliable for years to come.

2014 LML came in with a broken dipstick tube.

After diagnosing the concern, we traced it back to a faulty ICP sensor causing erratic injection control pressure readings. We replaced the sensor, verified proper operation, and got this legendary 7.3 back on the road.
