I am rebuilding a 1951 Lister CS 5/1 fitted with a CAV I.P and a Bryce injector.
I have bled the fuel line and I am getting squirts of diesel at the injector end of the hp fuel line, but the injector (known to be a good one and tested on another pump) fails to fire.
I deduce that the problem lies with the pump, either drawing air into the line or just failing to be able to produce enough pressure to overcome the spring pressure within the injector.
I am sure someone on the list is an expert on the CAV pump and can give me a full description of the likely failure.
Is this something I can fix, or would I be best advised I take the pump and injector to a diesel injection specialist, for repair and re-calibration?
I would be interested to learn from others that have experienced injector pump problems, and any advice on the inner workings would be appreciated.
