Show original supplier description
The Fuel-It! Universal DIY FLEX FUEL Kit provides a solution for adding an ethanol sensor and analyzer to vehicles where a direct plug-and-play kit is not yet available. This universal kit is designed for vehicles equipped with 5/16" fuel lines, which is common on most vehicles. This kit features a Bluetooth analyzer that connects directly to the supplied Continental ethanol sensor, offering multiple output options including Bluetooth for use with a dedicated app, a 0-5V analog output for systems like the JB4, and a 50-150Hz raw signal output. The kit includes all necessary electrical connections for power and ground. Users will need to download a third-party app for their Android or Apple device to utilize the Bluetooth functionality. Customers can choose between two Continental ethanol sensor options: part #13577429, which is the smallest sensor but lacks mounting holes, or part #13577379, which also is compact but includes mounting holes. Both sensors feature 3/8" male quick connect fittings. An optional accessories pack is available, containing six feet of 5/16" Gates E85 compatible hose (note: not compatible with Cam-Lock fittings), various 3/8" and 5/16" female quick connect to barbed nylon fittings, including elbow fittings, and a selection of Oetiker clamps in different sizes. Please note that Fuel-It! does not provide pre-purchase or installation support for fuel lines and fittings with this universal kit, as they are unfamiliar with specific vehicle platforms.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout.
