31 gallon from LMC. Get all the components, including their "anti-squeak" kit. Gonna need these rubber sheets. Replace the sending unit as well. Only thing with the new sending unit, ya don't get the extra fuel access port (used for direct exterior access to diesel to run auxiliary equipment like generators), but then again, who needs it?
I saved my old sending unit, outfitted with a new sock and stored away. New straps ( for the 31 gallon model). Read the LMC page carefully. I wound up with an extra new sending unit that is of absolutely no use to me. If you want it send me a pm.
Creating the access port was not necessary, just something the sick mind conjured up in my dreams, but may someday solve a giant pita if the sending device needs attention. Considering this hole is in a well protected portion of the bed, solidly made and very stout it was a good choice. Many of the new cars are coming with such access panels.
original guard/shield works well with new 31 gallon LMC tank, just a bit tight up top. With new tank be sure to install new filler hose while you're in there and make sure you're using a water proof heat seal butt connector for the sending conductor.
Cheers.
