At Triplet Diesel Injection-Waco, we can rebuild or replace most any brand of diesel injector. We offer testing on non-electrical injectors at no charge and we are always happy to let you watch and see for yourself what is wrong. There is a charge for electronic injector testing depending on what kind, call us for details. We carry most any kind of seals, gaskets, and hoses that you may need. Personal service is what keeps our customers coming back year after year.
