Restoring a 1973 Porsche 914/4 2.0L using D-Jet.
Arrived with the engine out so I have never seen how the fuel delivery was connected. Pump has a relocate kit to the front steering rack area. From what i can find the official pump for this configuration should be: Bosch 0 580 463 005 (Porsche: 311 906 091 D) - 3 port pump I have the: Bosch 0 580 463 016 (Porsche: 043 906 091 or 923 094 906 35) - 2 port pump I assume the 3rd port on the original (005) pump is the injector return line. Seeing that the 005 is very rare these days can I use the 016? The pressures and volume seem slightly different but not sure enough to matter with regulation down to I believe 2.0 bar? If I do use the 016 pump do I just plumb the FI return line directly back to the return fitting on the fuel tank when using the 2 port (016) pump? Does not routing the return through the pump mess with fuel pressures at all? |
