Ambac M50 Fuel Injection Pump Rebuild 50-2/4A-80A-9540A. This product consists of a complete factory rebuild of your M50 diesel injection pump found on MEP002A, MEP003A and other military and civilian units. Please note that this DOES NOT come with a timing button as timing must be completed when you receive your rebuilt pump. Also, we do not rebuild the older version of this pump which is a PSU pump that was previously made by American Bosch before the company was sold to Ambac. Your core must be an M50 and not a PSU core, please see photos for this product. We can’t accept a PSU pump as a core. Upon purchase of this product, you will be sent an email with detailed instructions on where to send your pump. Please ensure that you ship your pump with a trackable package.
Please allow 2-3 weeks total to receive, inspect and rebuild your pump. If your pump is not rebuildable, we will ship your pump back to you and will refund your purchase, less a $20 charge for shipping the pump back to you.
If your pump requires special parts, we will contact you to discuss prior to the rebuild. This is uncommon.
