Here is a picture of my application. The CSV "nose" should be as short as possible. Like the 914 1.7 that I used for quite a while. One or two fuel fittings is fine. One preferred.
The P/N pictured is 0 280 170 010 for a 82 Volvo and they seem to fail on me faster than the 0 280 170 018/017 for the 914 that is discontinued.
