Ambac M50 Fuel Injection Pump. Specific part number is 50-2/4A-80A-9540A. For MEP002A and MEP003A units and many other applications. This does not include the small timing button that varies with each installation. These units are REMANUFACTURED to OEM specifications and fully tested. They are cleaned thoroughly and stripped of paint and come ready for a 2 or 4 cylinder application. The price on this pump assumes NO CORE is returned. If you have a good core (It must be an M50 and not a PSU core, please see photos for this product.), we recommend that you have us rebuild your pump as it will be considerably less expensive. If, however, you would like to purchase this product and do have an M50 core, we will refund you $700 upon receipt of a REBUILDABLE M50 core. If the core is damaged or if a PSU core, we will NOT issue a refund.
If you would like us to rebuild your pump, please CONTACT US. This process typically takes one week to determine. Any core sent to us that is not rebuildable, will be sent back to you only if you pay return shipping. We will not be responsible for return shipping costs of any non-rebuildable core(s). Rebuilding costs typically run between $400 and $450.
