Fuel-It! BMW E Chassis Fuel Line and Ethanol Sensor Upgrades for the E60 535i and E89 Z4

We currently offer a variety of options to upgrade the fuel feed lines on your N54 and N55 equipped 535i or Z4 E-series BMW. All fuel line upgrades are 3/8" (AN6) and E85 compatible. In addition, we utilize our own custom fittings made specifically for your BMW so that you can maintain the stock connections at the HPFP, the tank, and the ethanol sensor should you choose to install one.

HPFP to the Tank:

This upgrade replaces both stock fuel lines with one upgraded continuous fuel line from the fuel tank to the HPFP.

HPFP to Port Injection:

This option adds the Tee line you need to integrate your port injection kits but retains all your current fuel lines and is compatible with the stock lines as well as upgrade lines and flex fuel kits.

HPFP to the Tank with Ethanol Sensor:

For those that want to run ethanol, we also offer this upgrade with an integrated ethanol sensor.

Port Injection Spacer to the Tank:

If you are running our port injection kit, this upgrade replaces the stock fuel lines from the tank to the engine bay and then utilizes a Y adapter to supply the HPFP and PI with fuel. Our custom fittings remove those tees and extra fittings for a cleaner high flow setup
