    I installed the FAST EZ-EFI in my car this past winter and did not change or modify my tank. When I installed the tank about a year ago, I did install a McRobb billet fuel sender with both a feed and return line input. While running carburetion, I simply plugged the return line input.

    During the fuel injection install, I hooked up my existing fuel line to the return side of the sender and ran a new line for the feed line to the frame mounted fuel pump. I have had absolutely no fuel feed issues. And I have run the tank down below 1/4 just to see what would happen.

    Here is a link to the fuel injection install.

    Update

    UPDATE

    I finished my LS1 install last week and used the same fuel sytem described above. Absolutely no issues. I ran the tank down to below a quarter tank again just to see what would happen and it still worked fine.

    A couple of concerns;

    Do you think the vibration of the fuel pump would eventually make the solder holding the tube to the sending unit break?

    And is the electrical connector for the fuel pump completely submersed in gas? That would make me a little uneasy
