I am considering installing the above tank into my '71. I am using an EZ-EFI system that uses the external pump provided in that kit. It works fine if the tank is more than half full, but stumbles from fuel starvation when the tank is less than half filled. It appears the fuel pump provided in the Spectra tank is inadequate for the EZ-EFI system. If so, is there a replacement pump that will work with minimal modifications?
