If the gear oil was changed, what type of oil was put in? If to has slip agents, the synchros won't be as effective.

Sounds like your dad is right. (I know...at 17 it's hard to believe! )
What you could do is ignore the fuel gauge and simply reset (zero) the trip odometer every time you fill up. Then refill at around 250 miles. After doing this a few times you should have a good idea of your fuel economy and probably use a higher number than 250 based on the size of your fuel tank.

Yep, it's been years since I've depended on a fuel guage to let me know if I need to fill up. The trip odometer is a much more accurate guage of how far you have to go on a tank. It will simply take running down a few full tanks until you get an idea of where that edge is.
Fill up, drive until you think you're getting close, and then fill up. you'll be able to calculate your maileage on the gas you used, and based on the number of gallons you put back in and the size of the tank, you'll have a good idea of how much gas was left in the tank. Then you'll have an idea of how much farther you could have gone on that last tank.
Knowing the range of your car on a full tank is a good thing!

Just a woman's voice here, Heather. The guys are right. I have always relied more on how far I've driven than on the gauge to tell me when to fill the gas tank.
I know when my Outback gets to about 280 miles traveled around town it's time to fill it up!

I don't know anything about the Subaru Legacy, especially not from 1995, so I tried finding any kind of illustration of the fuel tank. I didn't have any luck in my quick search, however, I saw this paragraph mentioning the sending unit at:
drivewire fuel pumps.
Summed up, it says it might be found from under the back seat or trunk. And I saw one at ebay. Looks like you might be able to get to the wiring connector at least and give that a check for looseness or any other problem.
They apparently cost around $37 at rockauto.com, for the kind I saw there anyway, but replacing it yourself (or Dad) might be trouble if you had to remove the gas tank or other such difficulties.
Maybe it wouldn't cost a whole lot to have done. I've never had one changed on any of my cars/trucks, only changed one out on a pontoon boat once and that's very different.
Good luck with that.
BTW, I use the trip odometer alot, too, mainly from keeping track of mileage. I just didn't think other people did as much as was said here. Still, it's nice to have a working gauge!
