Has anybody tried this? I have an MF 35 that I am going to try this on. I'm curious if y'all have seen improvement from it and how?

Never heard of it. Is it an injector/fuel system cleaner? I wouldn't expect too much.

Never seen it. It says for sick diesels. Is yours "sick"?

The snakes is Germany are very different than those in the US, They have a much higher quality oil.

It's supposed to be a complete fuel system cleaner. Cleans carbon deposits. You put your injection pump feed and return lines into the container and run until it is used up. My MF 35 with Perkins diesel dies on low throttle and I thought that might help break any deposits up that could be affecting that.

Arent the fuel in/out lines on your equipment steel? Its going to be very difficult to run them in&out of the container.
The reason its stalling is because the metering valve is sticking due to contaminants in your pump from the fuel your using.
Don't forget, what ever you clean out from your pump is going straight back to the tank.. so keep an eye on the filters.
I hope it works for ya..

Do it!
It's great stuff. I use it regularly in my VW diesels. I've also used it in a generator: it helped it immensely.
Here's an old How-To (from the diesel-heads at TDIClub.com):

As noted, use an in-line filter and you won't have to worry about any dislodged materials (not sure how anything could get lodged in today's high pressure fuel pumps).

It was pretty difficult to get the steel lines in there so I just dumped it in the tank but next time I will connect rubber or vinyl lines that will easily go into the container and put an inline filter. I don't think the metering valve is stuck, I just had the top cover off and verified that everything moves freely. For a long time there wasn't any fuel coming out of the pump and I thought it was the metering valve at first, but after further research I found that the plungers were stuck. So I used compressed air in the fuel inlet and opened one of the injector lines while cranking. It must have freed at least one of the plungers because it started getting fuel and it would run, but it had to be run with higher throttle or it would die.

If you take the top cover off again, look at the spring seat that rides against the MV, for a groove.
THAT GROOVE will make one stall in a heart beat. It grabs the MV and stops it from a smooth rotation.
You can find it by rotating the seat while its against the MV.. if it stops or skips you have a groove worn in it.
