Petcock Pro's

The first photo shows what came off my screen filter after letting it dry. Looks like a small amount of rust. Is this anything to worry about on a 11 year old bike? Or just clean and install? 
  The second photo shows the screen filter. The lower half of it seems squished and distorted. Is this normal? Can I clean everything and re-assemble?

Yeah, that looks normal. I wouldn't worry about it and just put it back in the tank.  Make sure the o-ring is correctly placed under the screen body and the body is fully pushed into the petcock housing. Failure to do this may upset the reserve feature of the petcock.

Thanks Ricky-D
