Jacqueline Shipe (A&P/IA) walks you through a typical Lycoming fuel injection system and the most common trouble spots to check if your engine starts running rough.
What is a throttle body?
The throttle body is made with a venturi inside; again similar to those in a carburetor. However, the venturi in a fuel servo is only there to provide air pressure settings to an inside chamber in the fuel control section of the servo, not to provide nozzle suction for fuel discharge as it does in a carburetor.
How does a fuel flow divider work?
It provides a central point for fuel distribution to each fuel line and nozzle. The flow divider has a spring-loaded diaphragm which opens with fuel pressure from the fuel servo and closes when fuel flow ceases. This setup provides a positive cutoff of all cylinders simultaneously at shutdown. (See photos 01 and 02, page 26.)
What are fuel lines made of?
Fuel lines and nozzles. The fuel lines connecting the flow divider to the nozzles are hard lines made of stainless steel. The last unit in the flow of fuel to each cylinder is the fuel nozzle itself. The fuel nozzles are made of brass and are very simple in their construction.
What is a fuel servo?
Fuel servo. The fuel servo is a fuel injection system’s fuel- and air-metering unit. The airflow to the intake pipes of the engine cylinders is controlled through the throttle body and butterfly valve in the servo. The pilot’s throttle movements directly control the amount of air entering the engine.

How to get a black poppet out of a hose?
the safest way to do it is to dip the last inch or two in a pot of boiling water for about a minute.#N#As soon as you pull the poppet out of the water start to work it out of the tubing with two pairs of pliers.#N#Be very careful not to scratch the poppet or break the hose. Don't squeeze to hard on the poppet or you will crush it an then you might as well buy the MFI kit cuz the cost about $80.00 a piece.#N#You will only have a few second at a time to work the poppet out before it needs to go back in the pot. Be gentle and it will come out.#N#If you are using a heat gun it only takes a few seconds to work it out, but if you over heat the tubing it will become brittle and increase the chance of making your problem much worse.
