There are many sources that say your truck uses a sending unit that varies in resistance from 0 - 90Ω . The stewart warner you listed reads 33.5-240Ω While this is a popular resistance range for the industry. I don't think it will work. My estimation is it will read from 1/3 tank to full where it is full most of the time and when it's actually empty, it will read 1/3 tank.

The gauge doesn't even read the tanks sending unit at all. The gauge just stays on E but when you unplug the sending unit and short the pink wire to ground, the gauge shoots over to Full....

But anyways thanks for the response.
