The kit uses the Zeitronix Ethanol Contect Gauge, GM Flex Fuel sensor, ethanol compatible braided nylon hose and stainless steel Oetiker clamps. Many of those who use Cobb can monitor the ethanol content from the actual Access Port screen. The Ethanol Contect Gauge can be mounted on the battery under the hood or inside the car.
The kit is plug and play and requires no wiring at all. The kit plugs into the factory SABS plug, requiring the SABS to be deleted and the codes to be turned off in the ECU. The hose that is provided runs to the factory fuel pressure regulator and you simply remove the line that is on it and replace it with the one provided. There are two supplied clamps that get installed on the hose at the regulator. The other end plugs directly onto the factory return line.
