The valve job will take the shop a few days and is under $2,000 in most cases. The rust in the fuel head, in my feelings is usually misdiagnosed. I have seen people take the lines loose and some rust comes out. This is normal for the fuel is taking out the rust from between the line and the nut. Don't worry about this one.
