Hi , My name is Fabien , 
I started in the restoration of my Ford Customline 54, I have recalibrated the engine block 239 Y ... rewired the car, but she refuses to move (PRN fordomatic dr lr) I have therefore dropped the box, refurbished disks which were blue, I have changed the tapes and oil type F) I have everything put together, and always the same, I have therefore redémonté and verified the valve body and the pump ... and I saw the hold of every pump damaged ... If one of you has this pump I am buyer at worst I tell myself that I will have a c4 if I do not find this reference 6551a pump ... Thank you to you!
