The sending unit is just there for the fuel gauge, so that couldn't prevent fuel from flowing.
Dumb question, but there is enough gas in the tank, right? The pump will run even without gas in the tank. Would still be a better outcome than having to replace that thing
Also, try connecting a smal piece of hose at the pump, perhaps your fuel line might be clogged with gummed up gas?

The ethanol in gas these days can be rough on a fuel system and doesn't take long to mess something up. I'd probably drop the tank and see what's going on. Maybe the sock is gunked up or something came loose in there?

My thoughts exactly! My buddy is bringing home a floor jack and some other stuff from his shop tonight I'll take a look tomorrow morning hoping it's as easy as a clogged sock.

How's that done ? If he sealed off both lines completely, that might work, but if he just removed the pump itself, there's no check valve anymore and that would probably be where your pressure is going. You'd just be pumping fuel from one tank to the other through an open hose.

95 doesn't actually have a fuel switching unit. Both pumps are always hooked up to each other via the fuel lines. Whichever pump is on is pumping pressure, the other pump holds pressure with a check valve. I think I just read that your dad took one of the pumps out ?

If you have dual tanks, and the selector unit looks like this one, the switch in the dash or the selector valve itself is faulty.

Sorry for not getting back sooner I read all the previous comments and I really don't know what's going on in the driver side tank (broken pump) aside from my dad telling me it's dry and he cleaned all the fuel out. But it has always had that fuel odor, people told me it's just because it's older, but I could never pin what was making the fume leak but it had ran fine before no dumping gas into the other tank the truck ran fine then sat in the garage for 5 months while I drove around a more fuel efficient car
