From time to time things happen. If your tech sheet was forgotten at the track, misplaced, lost or destroyed we keep tech sheets on file and can send you a replacement for a small fee. To send a replacement we will need your system number(stamped on manifolds or inscribed on plate systems), name, and the type of system. If the system was purchased second hand or through a dealer we will reach out to the original customer and verify it is ok to send a copy of the tech sheet to protect all parties. We can email or mail you a physical copy per your request. Once we receive the order for a replacement tech sheet we will contact you via the number you provide to collect the information necessary.
