GMG is now fully remanufacturing Ambac M50 pumps to OEM specs and fully testing them. Pumps come ready for 2 and 4 cylinder installations. We are providing a $50 core credit for any rebuildable core. You can purchase a remanufactured MEP002A-MEP003A Ambac M50 Fuel Injection Pump 50-2/4A-80A-9540A here.
We get this question a lot: So how to MEP002A units compare to their new generation counterpart in terms of sound level? The former doesn’t have a sound kit (ASK = Acoustic Suppression Kit) and the latter does. Listen for yourself. It is a material difference, but the MEP002A is not nearly as loud as […]
We live in a crazy world! I thought warm diesel engines should start easier than cold ones?! “My Generator Starts When Cold, But Not When Hot!” That is a true statement and remains true. The problem might not lie in the engine itself or the injectors or the injection pump or anything related to the […]
Below is a great video that concerns itself with answering this oft-asked question. Many military generators are only configured to output three phase electricity, especially the larger units including the MEP004A, MEP005a and up. Note that the MEP002A and MEP003A models output single phase 120/240V single phase power just fine and are not the focus […]
We have finally assembled what we believe is a relatively exhaustive list of past and present generators used by the US Military. On this page, you will also see links to two versions of the: STANDARD-FAMILY-OF-MOBILE-ELECTRIC-POWER-GENERATING-SOURCES-GENERAL-DESCRIPTION-INFORMATION-AND-CHARACTERISTICS-DATA-SHEETS-MIL-HDBK One version was published in 2010 (MIL-HDBK-633A) and one published in 1998 (MIL-HDBK-633). Both of these manuals have very […]
We have them. They aren’t cheap, but they will help keep your unit 110% in the winter and cold starts. These will also help save your starter from over-working (same goes for your batteries). Follow link to purchase MEP-002A and MEP-003A 24v Glow Plugs.
Many military generators have check valves in the fuel line system, often immediately after all of the filters, strainers, but before the injector pump. This prevents fuel from flowing backwards in the system and also helps the system hold its prime. The MEP-002A and MEP-003A units have a check valve located after the third filter […]
This is a great example of a MEP003A installed for home use. The unit is place on high ground that will drain well. Then the entire area is covered with crushed stone to aid in water transport and to minimize mud kicking up on the unit. 4 modest sono-tubes are sunk in the ground to […]
