Quick update - my fuel lines for the Corvette finally came in - so I tore the gas tank apart to swap out the fuel pump for the Z06 pump - and the new lines. I got everything apart and noticed that my fuel level sensor was messed up. It had a exposed wire on the bottom of the sensor - and the contacts are also bent the wrong way.
So I ordered a new one - and get to play the parts waiting game again.
Looking at the new sensor design - they flipped the wire contact points to the top. If I had not discovered this issue - it for sure would have caused me an issue in the future.
So maybe by next weekend - I might be able to wrap up this fuel tank swap and get the car back running - after that its engine tear down time!
