i am currently starting the restoration of my dad's '73 164E. I have cleaned and checked all the injectors and had the fuel tank refinished but i am concerned about the lines being full of "junk". I am also looking to completely replace all of the rubber fuel lines, but how should i clean the metal lines out? and exactly what type of hose should i use on the fuel lines. I am pretty sure that all the other hoses have been replaced before so i want to make sure i have the correct hoses installed.



thank you for any help

matt

    They have special hose for fuel injection systems. It takes higher pressure
    than carb type fuel hose.

    Spraying carburetor cleaner or lacquer thinner through the metal lines
    will clean them OK. If the fuel pump hasn't been run, it is probably
    gummed up also. You may be able to refurbish it with a couple of 1 5/16"
    x 1/16" O rings and appropriate cleaning. Alternate washings and running
    of the motor until it gets to where it will run after drying for a few
    hours may be helpful.

      Be very careful with your FI fuel pump. It uses the fuel to cool down the pump. Also, the commutator (the part that the brushes push against) makes a lot of sparks while the pump rotates and is exposed to fuel. It is no problem while installed, because there is no air to allow the fuel to burn (just like too rich a mixture stalls your engine), but there is plenty of air when the pump is removed from the car. It is a major fire hazard!

      Try soaking the pump with carburettor cleaner and leave it for a few hours. Then soak it again and allow to run out as jou spray in. This will flush dirt out. Once completely dry it is OK to run the pump for a few seconds, but not much longer as there is no fuel to cool approximately 50W to 100W of heat (as much as a light bulb).

      Have fun...
