I have started restoring this pen. However the piston is stick in the barrel I have tried easing it own with the metal rod shown however I don't want to apply too much pressure. It won't budge

Try soaking in water with a bit of dish soap or using a ultrasonic cleaner if you have one. Maybe soak for a day at a time then try again.

Agreed. I would give it a whizz in the USC

Would WD40 be a no go?

I’m not a fan of soaking vac fillers in water.
Try some naphtha and use a tube to push it out.

I absolutely agree that shying away from WD40 on most pen bodies is highly recommended. No problem at all there. However, I have previously whizzed a Parker 51 vac without damage in my USC prior to attempting to remove the pump. While people within the US seem to have reasonable availability of Naptha, here in the UK I'm not sure I know exactly what it is. It could potentially be lighter gas but that's guesswork on my part.

Isn't lighter fluid petroleum based? kerosene?
It's petroleum-based, yes.
None at all. It evaporates very quickly.

The 51 is made of Lucite, and is pretty tough stuff. Naphtha is a light petroleum distillate, so evaporates very quickly without leaving any residue. We use it in pen repair on a regular basis, and I have for almost 30 years without any problems. Its great for removing adhesive, and works well for unsticking stuck latex sacs. You may need to buy it at a paint store - you won't find it in any of the big box stores.
You don't want to pull on the pump. Don't use a solid rod - you can crush the pellet cup. Richard Binder came up with what he called, "the other vac tool, which is a piece of brass tubing that can fit over the pellet cup and push on the cone. Put a piece of dowel over the outside end. Push with one hand, pull gently with the other - but the naphtha helps.
