Here is some part number info for the injection metering pumps for the Lister-Petter LPW2 & LPW4 (aka Cummins Onan DN2M & DN4M):

Here's a picture of the guts of the Stanadyne version:
There are at least 2 different manufacturers that make these metering pumps with similar but slightly different designs.
Do both of yours have the same part # stamped on them? I can't quite tell from the pictures.
Are the batteries fully charged?
I don't have anything larger than an 803 personally, but I've read where low batteries that can cause problems with the electronics in the 805B/806B.
My preferred fitting is the Ace Roto-Mold 10897, which is a 1/4" brass bulkhead fitting with a groove and a viton o-ring. I've got them from tank-depot.com in the past, but they're occasionally available on Amazon, too. Never had a tank leak since I started using these.
I went with 50 amp plugs & receptacles for price and availability. I used the money saved from pin & sleeve to get heavier wire where it would fit: 4 gauge instead of 6 gauge, Type-W instead of SOOW. It's not perfect, but it gives me some piece of mind.
I think the filter base is very similar to the Donaldson P560382. The main difference I see is the location of the bleeder screw.
I put one of them on a custom trailer because it used the same filters as my 803.
You can probably find them cheaper if you shop around...
Alex, I had a stuck metering pump a while back. Here are some pictures from when I had it apart to clean it. See post #21. It wasn't the same problem you're having, but might be helpful if you end up cleaning your metering pump.
Here are a few more questions that might help us diagnose what's happening:
Is there any junk in the fuel tank that could be blocking / restricting fuel flow into the pickup tube?
What color is the exhaust smoke when it bogs down? (White, blue, black, clear...)
Are both batteries well...
What's the position of this switch (S6)?
To configure the voltage meter (M1) to measure 240 volts single phase, you'll want it on the position identified by the purple spot on the red arc in this picture.
I think a lot of the noise on my 802 was coming from the 4 lifting rings in the corners of the skid. I added a small piece of bubble wrap around them to quiet them down. I've also read about folks removing the little locking pieces that hold the doors open, since they tend to rattle too...
How many of the outback power inverters do you have? If you have 3, you could hook 1 to each pair of phases L1+L2, L2+L3, L3+L1 and should be well balanced. If you have 2, you could spread the load across all 3 phases (L1+L2, L2+L3), but not as evenly.
Never underestimate the value of hero...
Personally, I would go to the local John Deere dealership and buy some "Cool-Gard II", which is their brand of heavy duty coolant. It's what JD would put in that engine when it's in their tractors.
Curious... What kind of junk was in the hard line? Was someone in the past running it with bad/missing filters, or did the hardline corrode itself shut?
