Anything is possible, but not necessarily advisable, especially in a sub-zero environment. My dealer said he would forward the info to Fisker. As I said before, definitely something they should fix, nuff said.[hr]
Found a better source and pricing:

A fix that would cost Fisker $1.50 tops plus 5 minutes of labor (which probably is a minimum of 1/2 hour charge, but I am not sure how that works between the dealer and HQ) to pull the line measure, cut, insert the union elbow and reconnect the ends.
