Varnish in Fuel system...
 

Hello all,
I am a newbie to SAABs, my uncle has owned this 1980 900t since new, it has been stored last six years, 4inside last 2 outside. I can smell that nasty bad fuel/varnish smell. I figure I'll have to drop the tank etc. but really don't know much about this fuel system and what all I should be concerned with and what to clean, other than the basics. I am vey excited to get this car on the road, any help or suggestions would be great.
thanks
