I have removed the end piece and cut the metal pipe like the end of a epidermic needle and made 2 holes on the other side to avoid suction in case of piece of dirt getting close to it.
Now, I am getting 4.5 psi at the carbs.
The purpose of this blog is to keep my client posted on the progress and to help me for future reference. Feel free to contact me with suggestions or comments. Thanks for stopping by, Philip Caron, Citroen Restoration and Repair, Hamden, CT, USA, 203-230-5810 www.philcaron.com
