Before you buy

Earlier QSK19 engines with other fuel systems aren't covered. Check which control module is fitted to your engine before you order.

Your engine's dataplate shows the engine model, the engine serial number (ESN) and the CPL number. Compare those with the models above. If you're not sure, email us the dataplate details and we'll check for you.
