Fuel tank cleaning/removal

[Delorean17@xxxx]

Hello List,
I am replacing my fuel distributor and cleaning the injectors etc but I 
have not started the car yet. Since my car sat I would like to pull the tank 
out and clean it. How do I go about cleaning it? I removed the pump, and 
the tank really doesnt look that bad inside but the gas has a orange/yellow 
tint to it with a few small particles on the bottom of the tank. I will also 
be replacing some of the fuel hoses running to the back. does the tank need 
to be professionally cleaned? How do I go about removing some of the 
components inside the tank? any help would be greatly appreciated. 
I have the tank shield removed but I can not get the tank to come out. 
The fuel pump and filler line is removed and the tank is empty. any ideas? 
I've tried kicking it out from the top but it wont move an inch.

Thanks list
David
