Topping it off shouldn't be much of an issue unless you fill it first thing
in the morning, drive 1/2  mile, and park it in the middle of a tar parking
lot with no shade and it gets to be 100°.

 I had a leak on my '85, it was the seal around the sending unit/fuel line
thingamabob. There's a big threaded collar that holds the middle part in
where the fuel line and sending unit go into the tank and there is a rubber
seal between the it and the tank. Think like a Mason jar. I was able to go
in through the trunk and open up an access panel right above it to work on
it without dropping the tank. Make sure you don't have a full tank when you
open it up and make sure you blow off all the dirt and crud before
dislodging it into the tank.

 Assuming that's where your leak is, of course. :-p  You can open it up and
check pretty easily, anyway.
