Certified FAA/EASA Repair Station

Need your pump Overhauled?

CJ wants to keep you flying! We offer Overhauls and Exchanges for Fuel and Hydraulic Pumps on most applications. If you would like us to Overhaul your pump all you have to do is send it in for our experienced technicians to evaluate. CJ is not responsible for any lost or damaged fittings, hardware, etc. sent with the pump. Please remove and retain all items before sending in your pump. CJ does not re-install fittings or other hardware.

If you have any questions regarding Exchanges or Overhauls, call 1(866)920-2741 ext. 448, or email the repair station at repairstation@mcfarlaneaviation.com. Pumps needing overhaul may be sent to the Repair Station's Attention at McFarlane Aviation Products, 684 E 1700 RD, Building C, Baldwin City, KS 66006.
