In an effort to not mess around with a universal sender, i'm looking at something that runs around 7ohms full, 32.5ohms at half, and 95ohms empty.
Is this non-linear curve going to screw me?

From my general electronics knowledge, hell yes.
You might be better off using a microcontroller to alter the signal from a universal sender.
If i use a universal sender, i won't need to alter the signal. 
I was trying to use the OEM sender, but this seems like a pain in the ass.
Oh I had it backwards...so why not go with the universal sender then?
Depending on the shape of the tank in question, this non linear data you pulled may well be linear when actually in the tank. Run a universal and just deal with the non linear movement, just like 90% of cars with mechanical gas gauges did.
It really comes down to how much you care. If the tank is an irregular shape and it has to be accurate, a microprocessor setup is needed to linearize the output. If you just want a rough reading, any float type is fine as long as it reads zero and 100% okay. I used the capacitive type with adjustable empty and full settings, but not cheap.
