Is it possible to have a larger tank installed within the frame on a F350 dually 200l, the more capacity the better also would it reflect on the accurracy MPG readout. thank you

 

Check out Transferflow. http://www.transferflow.com/ They have both in-bed tanks and larger than stock replacement tanks.

 

Thank you for your help. I have ordered a catalog. Not to many stations with diesel, and many are extremly difficult to get into with a gooseneck horse trailer, and fewer station every year. Hard to understand with thousand of people moving into Northern California(Sonoma County)Whata Mess. Thank you again
