So I'm ordering this one for my 04 LB7. Wish me luck lol. I know they're not technically compatible but from what I'm tracking, I need a Spectra FN950 or similar filler neck, Dorman 645221 sending unit connector to adapt the sending unit and possibly a filler hose and vent hose. I'll update this comment whenever I get it installed and notate the bugs or issues I ran into. The purpose of changing it over is for the ability to use the big diesel pumps at the truck stops. 65 gallons is a big tank, and I have a fleet card which alot of times can't be used on the auto side.

Do you have or going to have a way to reprogram the fuel gaug for the larger. I see some companies do it for ram.

Will this fit with the spare tire fuel tank ? Or will there need to have a few wiring things to make it work ?

Will this tank work with a aftermarket fuel lift pump, such as air dog and or fass?

Does anyone know if this works with a b&w gooseneck. I connot tell if it has any clearance issues from the video. I have an 06 crewcab long bed dually.

SOOOO there are NO options for extended cab Long bed trucks 01-10. untapped market!
