As the suspense builds, the joy one feels when it at last gets tossed on the porch is immense!

Unfortunately, "Tis the Season..." & that joy could fade rather quickly ... if one looks at their Ring Camera, etc. and notices that a "Porch Pirate" made off with pkg's before you snagged them off your porch!
Thankfully I've got that situation under control on The Compound with multiple presence sensors that report to my phone & a great watch dog plus other deterrents!

We do not have that problem here in the German sticks. Maybe in the city, do not know. But in the boondocks, its not a problem yet.

What a surprise it would be if some porch pirate opens himself ( or herself ) up a brand new radiator bottle for "Christmas"
Bet he was hoping for a new set of Earbuds or perhaps some other electronics.... not a plastic bottle!
If it happens to get stolen, you may get it back with a sympathy note attached.

The shipment I'm waiting for is for the fuel filter and the seals that keep things dry in there.
So Napa has the filter, but the filter only comes with a gasket for the bowl, not the two for the thru-bolt...

Go to a good auto parts store. I always used O-rigs from a standard O-Ring kit. Should not be hard to match up.

They are a standard, albeit uncommon stock item, dash size 202. https://www.mcmaster.com/#9464K118 The bowl takes two.The shipment I'm waiting for is for the fuel filter and the seals that keep things dry in there.

It's a Napa 3348 filter.
Had three guys at the local Napa scouring the store for anything that might work. Two gave up and said they had nothing, third guy found an assortment pack that had one that looked like it would work. He robbed two of the assortment packs and told me to have a nice day - no charge.

I have everything to properly seal the fuel bowl in a kit.

OK, so with 37 total hours (since reset I believe) it runs and powers fine at 50% load. Fresh oil and filter, and two new fuel filters.
Increase it to 100% as suggested by turning on the oven in the kitchen, and it'll go just fine for 3 to 5 minutes, at which point the frequency drops off and then it chugs and wants to stall. I didn't let it go that far; when the freqs drop off-scale left below 55 Hz I open the disconnector and let it recover, then close the disconnector. That kicks off the oven so I'm back to 50% load and it's out there running fine like that.
I'm not sure if the oven is doing some weird cycling that takes it well above 100%. I tell the oven to heat up, put on my shoes (again) and walk out and monitor. It'll be at 100% by the time get there, and be solid at 100% until... the load jumps a little, the freqs drop, and it bogs down.
Checked the fuel drain and no water was present.

What kind of Electric fuel pump do you have?

Open the front door, left side. down low is the primary fuel pump. There are several different kinds. One kind was well known for loosing pressure under heavy load. When the set starts to die, is it a long slow death? Or will it shut off quick? Now, you are going to want to know what kind. Well, I have to look it up, and that might take a bit. But if its a longer slow drop off sounds like a lack of fuel problem.

I currently work for the Navy, was 20 years USAF, and I can tell you it isn't any different in those two branches of the military than it is in the Army. The books will tell you it's one or the other, but when you go to start the maintenance, you discover it's neither...
This is the fuel pump I have. The only markings are the ones you see. At least it's made in the USA.
In the second picture, is that another fuel filter there?

The arrow is pointing to a particulate filter. It can be backflushed and reused.

The E1074 is an Airtex pump.

The Airtex pump is better than the square Facet by far... but I have still experienced enough failures in it that I expect issues going forward with all of them. I would remove the hard line to the fuel filter, and have a clear line go back to an external tank and watch to see if it experiences performance dropoff after a while.
