I took my f/p guage off the car today and will be putting a new electronic one on next week. However, I need to drive the car before then but can not locate my old schraeder valve and fuel rail cap. Unfortunately, I can not find my original pieces and I've torn my garage and car upside down looking for them.
So, can I use just any S-valve and do I have to have a cap on it? Or, do I need to go to the parts store?
Help???
