    2,8L MFI - where to connect the fuel line of Webasto auxiliary heating system?

    Hi,

    during the installation process of my new 2,8L MFI engine we now have to decide the right way of connecting the fuel line of the Webasto auxiliary heating system which is already in the car as I am running headers.

    Because of the flow/ return fuel lines for the MFI system are both connected to the twin outlets of the front fuel tank we have to put a T-fitting in one of the lines. The question is now which fuel line to choose? I think I once have seen a '72 911 MFI with factory auxiliary heating system which had its fuel line connected with a T-fitting to the flow fuel line to the MFI pump which also would make much more sense for me from a technical point of view...

    What would you suggest here?

    Many thanks,
    Christian

    Seems to me there is a third fitting on the tank that will have a plug in it, I'll look tomorrow.

    Thanks!

    Our plan was to fit the fuel line of the Webasto with a T-fitting to the MFI flow fuel line BEFORE the electrical fuel pump - so the Webasto won't see any pressure. I think I have seen this as a 'factory' solution on a MFI car with factory auxiliary heating system but I might be wrong...

    I finally took the picture I promised of the fuel tank fittings showing the discharge, return, and third outlet (plugged in this picture) of the fuel outlet for the gas heater. Sorry it took so long.
