Thanks for the info on Modern Fuel Injection. I have a question you may be able to help me with, is there a fuel pump available capable of pulling the fuel from the top of the Pantera fuel tank similar to the arrangement of the original mechanical fuel pump? I have a very early 71 Pantera with an aluminum fuel tank. There is no drain fitting on the bottom of the tank to be used for a fuel pump supply connection. Holley has told me that the pump supplied with the Holley system must be gravity fed to operate properly and reliably with the Holley FI systems. So I am looking for an alternative pump rather than having to pull the engine and tank to put a connection in the bottom of the tank.
