Our Wildwood, FL Diesel Repair Facility

Southern Diesel Supply & Repair started in 2021 in Mount Dora, Florida. We outgrew that shop faster than we expected.

In 2026, we moved into a facility built from the ground up for what we do — 11,200+ square feet, nine service bays, and the equipment to back it up. Same standard of work. No shortcuts, no guesswork. Just more room to do it right.

If you value quality workmanship, proven results, and a shop that stands behind its work — come see the difference for yourself.

90-Day Labor Guarantee

If something we installed is going to have an issue, it shows up fast. That's why we stand firmly behind our labor for 90 days — and every part we install also carries its manufacturer's own warranty on top.

Repairs by the Numbers

Work We've Actually Put Behind Trucks This Year

This is a running count of the most common jobs that have come through our bays this year!

DCR & CP3 Conversion

A DCR or CP3 conversion replaces the failure-prone factory CP4 fuel pump with a more reliable DCR or CP3 pump to help protect the fuel system from costly contamination and damage.
Full Fuel Systems
5
A full fuel system replacement removes and replaces all contaminated fuel system components after CP4 failure or fuel contamination (DEF or gas) to prevent recurring damage and restore reliable operation.
Banks Monster-Ram Intake Kits

A Banks Power Monster-Ram Intake System replaces the restrictive factory intake horn and grid heater to improve airflow, throttle response, and eliminate the risk of factory grid-heater bolt failure on 6.7L Cummins engines.
Head Gasket Replacements

A head gasket replacement repairs the seal between the engine block and cylinder heads to restore proper compression and prevent coolant, oil, or combustion gases from leaking.
