I tried fitting the factory fuel tanks in today, and there is no way to make them work unless I drop the hangers. If I do that, the tanks are to visible (Not an option).
I am going to pickup a set of 1/2 short bed tanks today or tomorrow (Still waiting to hear from the guy who has a set) and see if those will work.
The 1/2 ton tanks are 4 gallons smaller (Each) which is kind of a bummer, but once I have this truck running at 20 MPG, I don't think it will be as big of a problem.
More soon to come!
