[Ford-ferguson] 1952 fuel tank

[Rick]

Greetings to fellow ferguson owners.
I am new to owning a tractor and have the pains
of a rusty and sediment filled tank clogging up the 
fuel line every hour requiring frequent draining and 
cleaning.
Is there any chance that these tanks are available in
poly now? It seems everything is made of plastic these days.

also I am looking for the standard carb adjust settings for the float
screw and mix screw.

any help appreciated

Rick
