Linda, read through this old post, and the link inside to a post at renntech. It may help/assist you.
In the future, when you get everything up and running again, use the Chevron fuel cleaner with Techron. It is a black bottle and comes in treatments for 12 and 20 gallons of fuel. At least once a year would be good.
Post some pics of your Boxster soon!
