I pulled the forward metering pump, poured some fuel in the feed fitting and covered it with my finger, then pumped the actuator with my hand. I can feel suction on the feed fitting, however nothing was coming out the "fuel pipe end" unless I loosened the "delivery valve holder" more than 1/4"...
Hey all, I've had this MEP-802a for several years now and it has been very reliable. I try to load test every month, but honestly I forget and sometimes it goes 2-3 months between tests. Well I pulled it out yesterday after sitting 2 months and it cranks but won't fire.
Electrically...
Pretty much. Don't know why, but diesel seems to last longer in metal containers vs plastic ones.
One year in storage in a plastic can and I have all sorts of nasty stuff growing in the can. Metal cans and transfer tanks, the diesel last up to a year without signs of biological growth...
I'm not quite following.
If a generator is 3-phase, operating at a fixed speed (1800 rpm), then power absorbed is a function of torque on the rotor. Torque is a function of the combined load on the 3 phases. For example, shouldn't a 15kW generator not load each phase at 5kW? (average)
Now...
I would agree, even being off grid, its nice to wire the shop like normal and then bring in power through a twist lock connector. (As opposed to mains power) My friends have an off-grid cabin wired this way.
That said, I have a portable setup I use with my 802a that works pretty well for...
I wish I had a 2nd 802a or 803a on hand. I'll have to make due with having a spare set of filters and belt, and 60 gallons of treated diesel. Highly unlikely it will be needed where I live, but it's nice to be prepared. I keep a small Honda inverter generator as complement to the MEP.
Does anyone know what the filler hole thread dimensions are? I'm having trouble finding a drawing or specs for the threads on the old WWII style Blitz Jerry cans.
Specs or drawings on EverySpec have been superseded by the MFC sepcter can spec. I believe I'm looking for MIL-S-1283 or similar...
Yes, I don't have one, but I'm tracking one down. I also have a friend with a 3500watt Predator Inverter generator.
Here is a screen shot from a YouTuber testing a Coleman 5000 watt open frame, 3600 rpm generator.

Most folks know the MEP units with brushless genheads make clean power. However, I've always wondered how clean.
I used a Rigol DS1054Z scope with a Micsig differential probe to do the measuring and screen captures. (So I don't blow up the scope)
For baseline reference, here is incoming...
Google or Amazon "California Twist Lock".
There is not a standard NEMA 50A 120/240V twist lock. The defacto-standard is the CS50 (California Standard 50 A). These are commonly found on spider box power distributions.
Here are some examples:
This is a female receptacle...
Something's wrong with your pump or 802a. Mine starts a 3.7HP air compressor. Generator grunts hard, but listening to the air comp, you'd never know it was on gen power.
Maybe your well pump is partially shorted. Get an amp clamp that can measure peak amps.
I bought a R2.8 Cummins (ISF 2.8 ) for a truck repower project. Lot of China made parts. R2.8 assembly is suppose to happen in the US. The engine has a generally good reputation. For reference, this is one of their joint-venture factories in China.

Thanks for the great report, especially fuel consumption numbers.
I have an 802 now, but still shopping for an 803 to run the central A/C if necessary. (I have window unit for emergencies right now) The 831 is interesting and I would still like to play with one. We don't have many power...
