I've put my engine back in the car and want to confirm the FI fuel routing. I've looked at PP/Dave Darling's diagrams, but would like confirmation:
1. large (9mm) plastic fuel line from firewall connected to fuel filter 2. fuel filter connected to fuel pump at (S-suction) connection 3. (D-damper) connection on fuel pump connected to fuel rail on passenger side, rear connection 4. (R-return) connecton on fuel pump to Y connection 5. Y connection to small (7mm) plastic fuel line from firewall 6. Y connection to fuel pressure regulator 7. fuel rail on passenger side, front connection, to fuel rail on driver side, front connection 8. fuel rail on driver side, rear connection, to fuel pressure regulator 9. fuel rail on driver side, middle connection, to cold start valve. Also, I'd like confirmation on the electrical connection to the fuel pump: 1. black/red wire to the + side of fuel pump 2. brown wire to the - side of the fuel pump If I wanted to test the fuel pump outside of the car, I should be able to connect a positive wire to the + of the fuel pump, then to the + side of a battery, then - fuel pump to - battery. I could then connect the (S) fuel line and place in a container of gasoline. Then place the (D) and (-R-) fuel lines into an empty container. When I connect up the electrical lines, I should get the pump to hum and run fuel through the pump. Also, if I turn on the ignition, I should be able to get voltage across the black/red wire and the brown wire, correct? Finally, has anyone successfully found a shop that can rebuild these fuel pumps? -- Rob |

The hose from the plastic supply line to the filter is 7mm on one end, 9mm on the other. The part number is 914 356 525 00, and it's readily available from your local Porsche dealer, although they may have to order it. Around 25 bucks.
DO NOT "make something fit". Fire's an ugly thing and, odds are, you'll have one if you cheap out on the job. The Cap'n |
