Long-term storage recommendations for VEP/CR/PD components?

What is your recommendation if someone plans to store (used) fuel injectors?
I was thinking about completely coating the elements with diesel and then vacuum-sealing them in a bag using a heat sealer. What are your thoughts?

If the diesel doesn't dissolve the film, or, in the worst case, triggers and the film then gets stuck to the nozzles...

Sounds good.

Thank you for the worst-case scenario, Martin! I would, of course, first conduct a long-term test to see which film makes the best impression. It would be best if I bought oil-resistant injection element bearing film at the hardware store.

How about using Ballistol as a gun oil?

It is supposed to have excellent protective functions for metal surfaces.

offtopic: Regarding fully automatic weapons, I can confirm that they don't jam after a few magazines even under combat conditions, but that's because the weapon is soaked in oil and not just lightly oiled. An AK74 will still function even when oiled, even if it has been in water, which is why we discard German equipment more quickly under fire .

However, these types of seals are not used here either. My concern is that the oil may cause the O-rings in the PDE to swell.

Okay, you're probably already getting a new set of seals anyway, but try to remove Ballistol from somewhere . That's a task even with brake cleaner! Diesel would be ideal because I can simply wipe the part verschandeln with a non-fibrous cloth before installation, put on new sealing rings, and install it.

And - In fact, there are definitely oils that are not compatible with diesel fuel.

...well, then take the seals off, and in 20 years, you'll be able to get them at the VW Historical Center, because no matter how you store rubber, it will degrade .

The tip was impossible to miss . I'm only concerned about storage periods of up to 3 years. I simply think it can't be healthy if an element doesn't have any juice for that long. Wasn't it even the case that, in some different types of DKs, the "needles" could become stuck?

I was only talking about the seals; you can definitely still get those from VW in 3 years, and they'll likely still be quite good.

...I store various "spare parts" from my collection of classic vehicles (okay... maybe it will be a collection someday, but for now it's just 4 motorcycles... mmm, by the way, does anyone have a worthwhile Fiat 500 that I could restore for my wife???) by wrapping them in oiled paper and coating them with a layer of WD-40.

Okay, these aren't highly precise parts, but there's no rust .

The test oil, which is used for adjusting fuel injectors, is also said to be very suitable for long-term storage.
It doesn't become sticky and is compatible with diesel fuel. However, it's not cheap, especially if you need larger quantities, for example, to preserve a VEP (vacuum evaporative process) system.

Cheap 15W-40 oil, which you can get in a 200-liter drum for just over €1/liter . As a corrosion protection, I mean, it is completely sufficient...

Diesel is not a preservative! There's too much water in it. Over time, this water is released through corrosion processes, which can lead to rust problems. As recommended, test oil is a good alternative. Alternatively, you can also use mineral hydraulic oil (HLP 46), which you can store in a regular container. This product is corrosion-resistant and compatible with seals in the long term.

Thank you very much for the feedback! @Diesel_Rudi:

Please don't forget to remove any diesel fuel from the components before storage (possibly by disassembling them), as otherwise, it cannot be guaranteed that the diesel will ever drain out, even if you try. You may need to press out the elements or run them one last time in the engine with hydraulic oil 46. Then you'll have peace of mind for years.
