I thought I would share. We are going through my build now and one the first things was to swap the in-tank pump. Right away we realized that the pump setup from my car was not going to work with the ZL1 pump.
It appears the choices are as follows:
1. Take the pump off the ZL1 unit and install it in the original LT1 unit.
2. Add a crossover kit and an extension basket to make the zl1 pump work with the the SS.
We didn’t realize there was a different configuration on the SS Vert.
Here are pictures of the ZL1 pump and my original unit. Parts required are being shipped Monday (I will try to get pictures when they arrive.) I originally posted in another place because I didn’t realize the problem was related to the vert.
