95 Rodeo Fuel Gauge

Hi, I'm a newbie and just purchased a '95 Rodeo 3.2L 4x4. The vehicle is in great shape except that the fuel gauge is a little wacky. It works fine until it's down to 1/4 tank and then the needle basically stays there and the empty light flashes intermittently. Is this simply a fuel sender problem? If so, does anyone have the part number or knows the best place/price to get one?

I did search and see this as a common problem for '98 and up but couldn't find anything for my generation Rodeo.

Thanks in advance!
