morning all,
i am about to fit new MFI red lines complete with the injectors etc, also the red plastic return line under the fuel lines...
i am assuming theses lines on the car will be under pressure? (although i am changing these because the return line the previous owner had used is rubber hoses and this split causing a fire which melted (did not burst) the re fuel lines to injectors, so there may not be pressure in that return line...

whats the best way to remove these all from the metering unit without spraying fuel everywhere?
was thinking wrap rags or a towel around the metering unit and crack the banjo nuts slowly one at a time?
thanks

or is the system not under pressure until the fuel pump/ignition is turned on??

The system will retain residual pressure for a while (half hour-hour usually) but otherwise thats the purpose of pump prime on key on, to get that pressure back up

Yes thanks I just changed all the lines over...cold start line is seized to the mfi union end so will get that took off Tommorow at local pirtek. Hopefully I have no leaks......

As long as you use new washers its pretty hard to get a leak. Soft alloy metering unit plus copper washers, they'll absorb most shapes and seal up
