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 |

Daves drawing is right on from all accounts. Assuming of course we are talking about a 2 liter. Rest of the assumptions look good to me except:
Power across the fuel pump is only applied for 1.5(ish) seconds after key on then not again until the starter is engaged or the engine is running. To get constant power ground pin 3 on the 4 pin connector on the relay board. Probably a good idea to connect the return line from the pump to your output container in your out of car test rig. You can get bypass fuel coming out there particularly with air in the system. These pumps don't pump air well so you might want to get the pump below the gas container and give it a little manual prime. I haven't found a rebuild source. No rebuild kits either. You do see rebuilt pumps for sale but where they source the rubber parts from seems to be an industry secret. |
