Have u ever installed duals on a Cadillac CTS-V...I here it is a pita to install any different type pump in my V. because of the way the tank is engineered.

 

This^^^

 

I do a dual intank kit for the early CTSV's. Not exactly easy to build, but I have done a few of them. Give me a call if you want to discuss.

 

with the Dual ZR1 pump go in a normal C6?

 

The C6 era ZR1 only uses one pump in the drivers side tank, not dual pumps; and it is not compatible with a base C6 electrical system

 

why can't u just drop a 20gal. fuel cell in the trunk and run your pump or pumps..It sounds a lot easier....also couldn't u still run the stock pump in the stock tank [ u would have almost 40 gal. of fuel and added pressure and insurance] yes or no
