Hydraulic Cylinder Seal Configuration Back to Back Leaks

[ESTinker]

I'm trying to fix a hydraulic cylinder seal leak where the fluid has 1 entry/exit at 3,000psi and the other side open to atmosphere. There 2 U cup shaped seals (loaded with O-Ring) with a back to back configuration. I believe this creates a pressure trap and causes premature failure of the seals where hydraulic fluid leaks pass both seals. What's the best option to fix this? I was thinking about:
1. adding an O-Ring between the back to back seals
2. Replace the 2 U cup seals with O-Rings and add a U Cup seal in the middle
3. Switch both U cup seals towards the high pressure side (flip the direction on the rear seal)
4. Remove/Unload the rear O-ring on the atmosphere side to unload the seal

Firt it must be said that with moving idraulic seals there is always an oil film covering the surfaces to prevent damage on the seals.

Not having a guiding surface is not so good, I will advise to use a seal of this type

with the addition of a wear ring

to have the pistn guided.

If you can't modify the geometry, facing the two seals toward the pressure can be useful. But the addition of a guide ring is recomended.
