Fuel Filter Green Particles

[NevSpit]

Good evening all.

Working my way round a few jobs on the Spitfire (MKIV) and changed the fuel filter as it was past its best. Once it was off I noticed these green particles in it. Anyone know what it is?

 Thanks

They look a bit plastic.

But I used a length of copper tubing in the fuel supply on my engine rig.   It clogged up, with green stuff, and I was amazed to find that the dip tube in my improvised fuel tank ( a plastic 5L can) was thicj with green verdigris.

You might chek if there is any length of copper tube in yours.

Wonder if someone has added a shot of this stuff, and lost part of the container into the tank as well as the additive? The end cap snaps off and is easily dropped into the tank...

Opened up the filter tonight and they do indeed appear to be slivers of softish green plastic. The green petrol can suggestion appears to be the most logical although I can’t remember using a ‘new’ one in the past that hadn’t had a good slosh of fuel in it before. I haven’t used one of the green additive ‘shots’. There is a new filter in it now so will see if any more comes through. 
As always thanks everyone.
