I'd like to add a few very important facts to know about the triple pump hat that I think some people might not know about. You don't have to run all 3 pumps with this hat for it to function properly. The 3 pump hat can run 1, 2 or 3 pumps. So for those GT500 guys that want to upgrade their fuel system but not add the 3rd pump you can run dual pumps in the hat with your stock dual FPDm setup without having to run the MDM. You also have the ability to adapt the Fore hat with your stock fuel lines with the hat to stock line adaptor upgrade for $45.00. This is great for those that want to remove the restrictions of the stock assembly but still run the stock lines and rails. You can always add on upgraded lines and the additional pump and MDM at a later date when needed. So as you can see the Fore hat for the S197 can be utilized in many other ways then just a triple pump system. It's versatile, easy to install and best of all performs!
