This is a complete plug and play kit to install a Bluetooth ethanol sensor in your F-Series BMW. (Check compatibility for your platform below)

For your fuel line upgrade, choose the option that supports your current configuration.

  • HPFP to the fuel tank: (Stock)
    • This upgrade replaces both stock fuel lines with one upgraded continuous fuel line from the fuel tank to the HPFP and adds the ethanol sensor.
  • Port Injection to the fuel tank:
    • If you are running our port injection kit, this upgrade replaces the stock fuel lines from the tank to the engine bay, integrates the ethanol sensor and then utilizes a Y adapter to supply the HPFP and PI with fuel.  Our custom fittings remove those tee's and extra fittings for a cleaner high flow setup.
    • Phoenix Racing Manifold to the fuel tank:
      • If you are running the Phoenix Racing Manifold port injection kit, this upgrade replaces the stock fuel lines from the tank to the engine bay, integrates the ethanol sensor and then utilizes a Y adapter to supply the HPFP and PI with fuel.  Our custom fittings remove those tee's and extra fittings for a cleaner high flow setup.
    • Non-Fuel-It! port injection to fuel tank:
      • Choose this option if you are running a port injection kit that we did not manufacture.  This kit includes a longer 18" feedline from the Y to the port injection rail.  You then cut the feed line to the length you need and install the included -6an female fitting or -6an female elbow to make the connection to your port injection rail.

    All of our kits utilize our custom billet aluminum fittings to integrate with the stock fittings so no modifications are needed.

    *For the BMW F-series PWG JB4 platform connect the white wire to position #16 on the JB4 25 pin harness. Select WMI page option 15/16 input to enable.

    *For the BMW F-series EWG JB4 platform connect the white wire to position #14 on the JB4 25 pin harness. Select WMI page option 15/16 input to enable.

    *These kits are available for off-road use only

    *Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated your ethanol readings may be artificially elevated.

    Nice tire sealant.
    Size: 32 oz
    This seems to work very well. I will say that it seems to be pretty important to move the wheel around as soon as you can to distribute the product within the tire. I was held up for a few minutes and the Liqui tube seemed to start to set up in one spot and made the tire out of balance so I had to work quick to get it to distribute to the other parts of the tire. It seems to have worked though and so far the tires are holding air very well. I will be interested to see if it lasts for a long time but so far so good.

    This stuff works!
    Size: 32 oz
    I was sceptical but wanted to avoid replacing 2 rear tires on my zero turn mower. The tires were leaking air and had bad sidewall cracking. I found the use of the product to be easy and quick. I aired up the tires and rode around the yard a few minutes to distribute the product in the tires. It has been 4 days and both tires remain aired up. Previously both tires would already be flat within this timeframe. Excellent results for me!

    #1 Tire Repair
    Size: 16 oz
    This stuff is Fantastic. I have a riding lawn mower and one of the front tires, which is small, had been running low for a couple of years, we took it off. to fill it with the liquiTube and you could see cracks all around the outside of the tire. The liquid tube oozed out of one of the cracks and sealed , immediately. My brother rolled the tire around real good before we put it back on the track lawn mower. It has been 3 days now and today I mowed for 1 1/2 hrs and the tire as full as it was the day we put in the LiquiTube. This stuff is fantastic, it really, really works!
