Finally how can I diagnosis my fuel accumulator its a two line in only version?
Thank you all in advance for your help.

Emi,
I am wondering how did you determine that the system is loosing residual fuel pressure? Did you measure the residual pressure? The FP for '75 is suppose to run when ignition switch is @ ON position (not start). Is this correct? The fuel accumulator is easy to test. Either pressurize with air or liquid to test the diaphragm. A broken or defective diaphragm would leak. Remove the tiny screw at the bottom during test.
