Any fuel additives to help slow a leaky cold start lever seal?

Sorry I keep posting dumb questions. I searched, but didn't find much on the topic. My ecodiesel pump is leaking at the cold start lever seal on the back side of the pump. Some people said you can maybe temporarily seal with biodiesel, or adding a gallon of e85 to a full tank of ulsd. My question is, is there any actual addivites that are made for this type of thing that work? I had thought about running some two stroke oil, but I'm not sure how much to put in. I am familiar with tdi's, but when it comes to the older engines I'm kinda unfamiliar. Any help is appreciated, thanks.

All I can add is my own experience, and that would be is it never works out. And a leaking pump with a bad seal is probably in rough shape with lots of crusty unpliable old seals that also need replacing.
Learned my lesson after my first 2 pumps. Was trying to save $$$ on these cars that are daily driven and got so sick of the leaking diesel that leaves puddles on the ground and eats coolant hoses.
So now if I have a good running pump and plan on daily driving a vehicle, I break the pump down and clean and reseal. So nice not having to worry about it.
My experience with all stop leak crap has been bad except for the pellets for coolant leaks? Never had the power steering or oil additive stuff get rid of even the smallest leak.

Yeah, I wouldn't waste time with secret-sauce, when sealing an IP is not difficult.

I am planning on installing a turbo pump, but there is no point in taking off this pump and doing a reseal just to swap to a turbo pump which will probably need resealed anyways. I just want to start driving the car more, but it scares me having it leak diesel everywhere I go.

seal kits are cheap and pulling the injection pump is not very hard.

Yeah I saw that the reseal kit from bosch is only 26 bucks. I unfortunately have no experience doing a reseal, and also, even though there is some good write ups online with pix, I am not able to get enough from pictures alone. I need to see somebody doing it, so I will probably have my friend who is in school for diesel tech do it.

I spent one year in diesel "tech" school. I was mystified at the (up to ) $5,000 tool boxes the other guys had.
The only tools they ever took out of the boxes to "repair" stuff was the screwdrivers and hammers! Mostly hammers.
Learn to DO IT YOURSELF. sheeeesh.
(OK...I'm fibbing. ONCE this one other guy took out a wrench and twisted off a bolt with it.....)
And AGAIN: Ok, if you are smart enough to know there is a chance you can mess up, well, hey....THAT'S 9/10 the battle.
It's those guys who are "too smart" to listen, that a man has to look out for!

I've had success removing the feed line and sticking it in a jug of cheap ATF. Run the engine until the pump is full of ATF and then let it sit for at least 12 hours. Then just start it up and carry on and see what happens.
The ATF swells the seals and provides a good temporary fix. However, I've also had this make a leak worse, but that was only once.
