I just bought a 2007, F-150, V8 5.4,Triton, ext. cab with a 6.5 foot bed. GASOLINE powered not Diesel. The fuel tank holds about 26 gals. Can I install a larger capacity tank, preferrably, under the bed, either Ford or after market?

 

Were optional tanks offered on your truck when new? Would that be of interest or help?

 

There was an optional 38-40 gal gastank option on the 07's. Question is if it was available on the short box or not. I have it but I also have a long box 07.
