Holley now has these EFI fuel pumps that drop into a fuel cell. Seems like a clever idea to me. Cleans up the plumbing in the trunk or under the car, especially if you mount the regulator next to the fuel cell. Then you just loop a short return line back into the fuel cell and only have to run a single high pressure line up to the engine.
