    MEP-016B / 701A Battery Conversion

    I have some more in process but still a ways out. I'll post up when I get close and the paint is drying!

    Picked up 6 MEP-802A gensets and will be documenting making them all runners here

    Per the manual, when you pull the pumps you must leave one pump in to keep the rack engaged. Otherwise the front of the motor may need to come apart to reset the rack. Also, the pumps rorate on serrated clamps. The rotation sets the fuel balance between pumps so each cylinder contributes...

    Source for Electric fuel PUMP for MEP-802 & 3

    Check out the big auction site for 24 volt pumps. There are several pretty cheap. On the 802a and 803A those pumps just push the fuel in a circle so the exact flow or pressure rating is not a big deal. Just get one that has that cube shape with the right connections and it should work fine...

    Electrical Gremlin Shuts 802A Down

    Either your float switch is bad telling the controls that the fuel is too low or the magic box that the float switch is connected to is bad. You can run it in the battle mode which will bypass the shutdowns. The float switch can be pulled out and checked and adjusted if the float height is...

    MEP-701A Fuel Pump Priming Question

    The hose ends should be 37 degree JIC -4 size. Any hose shop should be able to build a hose. Bring in the old one for them to copy. You might try using the hose from the aux pump to the top of the tank if you want to get it running. It's probably way too long but it should work as temporary. I...

    rebuilding MEP802a fuel injectors??

    The shims set timing, and as you say must go back the way they came out and may be different on each cylinder. Fuel rate is controlled by rotating the pumps. The pumps should go back at the same angle of rotation as they came out. One pump must be left in at all times to keep the rack in...

    MEP-701A Fuel Pump Priming Question

    The check valves have to be in the pump as they are not elsewhere. Not sure what they look like as I never had a pump apart. There are repair kits on the big auction site maybe they have pictures of the parts. Although often practiced, it is not advised to pour fuel into a filter housing due to...

    MEP-701A Fuel Pump Priming Question

    I'm sure the hole has a purpose. To fill the system, I put my finger over the return in the tank and use a mighty vac on the bleed screw on the filter cover to draw fuel into the filter housing. Then it's only a few primer pumps to complete the process. Your pump might be air locked. If it...

    MEP-701A Fuel Pump Priming Question

    I've never had one apart. (And I've got about 35 of these running in the last 2-1/2 years) They do leak backwards over time and loose prime. Some in a few hours others take weeks. With the cam lobe off the plunger it takes 250 - 400+ quick strokes of the lever to fill a dry filter and get air...

    802A Parallel operation ???

    All these threads ever talk about is getting the two sets synchronized. If there is not a master and slave governor and a master and slave voltage regulator then it is hightly likely a voltage regulator will be smoked. Load is a function of fuel position and with mechanical governors and some...

    802a electric problem

    Just to confirm you are checking the circuit interrupter relay which is the big one under the top lid not in the box behind the gages. There is also a relay behind the gages that powers the big relay. check it too. Download the manual and see what it has to say. Chances are it will be a lot...

    MEP701a start up, Click, Click, Click

    That solenoid stutter is a classic problem with several possible causes. first, before cranking the solenoid should snap on and stay on. Whether it stutters or not the engine will crank if the switch is turned. Battery connections are usually a problem, easy to clean. Make sure they are tight...

    MEP802A load test ?

    I never load banked a gas unit. I did load bank the 3kw diesel Pow'r Gards that you might see in the auctions from time to time. The weight of the gen end is less than half the 3kw 016 series. Their gen end is equal to a quality consumer unit like a Honda. The Pow'r Gards do not like...
