I finally figured out where all of the oil on my right front crossmember and frame is coming from. There is a fitting on my fuel pump for a vacuum line that is spurting oil.

I have an electric wiper so have no use for the vacuum line. Would there be a problem if I put in a short piece of copper line (crimped) and a fitting to block off the line?

The fuelpump works fine for getting fuel to the carb, I don't want to risk ruining that part of the pump.
