Do I need to wire the wires together that are no longer “connected” by way of the frame rail fuel pump. Seems obvious to me that you DO need to but wasn’t sure if there was power going to frame pump separate from the power going to the in tank fuel pump.No, on swapping the gauges, just use correct sender in the tank or fix yours, read here: https://www.fordification.com/tech/fuel-sending-units.htm
You can buy new ones, but not cheap, Google: 1987 Ford Ranger fuel level sender
I just used 1987 because Rangers all used same one that year
For Fuel Level there is just 1 wire from tank to gauge on any year and any model, sender and gauge are grounded separately, so wiring is not the issue
Swapping to an 1989 gauge or cluster would end up being way more trouble that its worth
If you want you can mount another fuel gauge in/under the dash, that uses Ford 1989+ OHMs so you can use an 1989+ sender
