Default Fuel sending unit wiring

Long story short, I was installing a racetronix fuel pump in my early 03 corvette, and I broke the sending unit. I took it off and I left it alone till the new unit came in. But I forgot to take a picture of the orientation. Anybody know how this wiring goes?

I'd like to bump this...if this wiring is reversed, will it cause problems?

I just did a racetonix pump kit and now with a full tank (gas station will keep shutting off) my gauge only reads a touch under 1/2 full. I'm suspecting my DS sender (which was removed for pump install) may be wired backwards?
