Fc owners would u guys recommend flushing my fuel tank if my cars been sitting all winter say almost 6 months at half tank?

 

No. If the car has been properly stored then there should be no reason.

6 months isn't too bad. Fuel has begun to break down after the first few months but most certainly has not reached a point where it becomes varnish sludge. Just get some fresh fuel in there and run through a full take of good fuel before you drive the car hard.

 

+1.
I think I'd recommend filling the tank next time though.

 

And maybe use a fuel stabilizer.
