We removed and cleaned the fuel tank in my son's new to him 914. Also changed the fuel lines to stainless steel. Other than setting valves, nothing mechanical or electrical was done. Ran fine when parked a month ago.
He tried to start the car and nothing. I'm suspecting fuel, but I am new to fuel injection and don't know where to start, except to see that fuel is reaching the fuel pump. (I'm a webers on 912 guy) Does the injection system have to be bled when it has been reduced to bone dry empty like this? How is that done? A search of the threads has turned up nothing. This will be tomorrow's project. Thanks- Rob |

The reason you dont need to bleed is that there is a return path, self bleeding.
My story, I have a 1.7, the PO moved the 3 port pump up to the front. Before the year or so restoration I have been doing, I got the car running in this configuration. Fast forward to some period of time during reassembly, I re plumed, the 3 port (all new lines), wont run. Note when I got the car initially running, I took the pump apart, cleaned it, and even bench tested and ran it. I have no idea what happened to the 3 port, during the year of sitting, but I cut my losses and switched to a new 2 port, re plumed, and now it runs again. |
