hi im usually a vw guy but i thought id try my hand at a classic Subaru so i bought one that has been sitting for 20+ years. i just got it running but i would like to remove the fuel tank and clean it are there any tricks i should be aware of? ps its a 2bbl carb car idk what size the engine is but im sure that doesn't matter for fuel tank removal its a dual range if that makes a difference

Rear diff and moustache bar needs to come out. 

Disconnect all fuel lines/hoses and vent tubes. Disconnect the filler tube. Unbolt and drop out. 

I recall there being a difficult bunch of hoses that pass through the chassis rail that need to be disconnected. Other than that it wasn’t too hard to do. Watch out for all the crud on top of the fuel tank falling as you drop it out. That was well over a decade ago now  

Cheers
