So I just installed a new electronic fuel pump. All lines got drained when I took the old one off. How do you go about primeing those lines with fuel. I can crank it with starting fluid but there is no gas getting to the injectors and it will eventually shut down. Is there a trick to it?....Thanks in advance.

If you pulled the tank, then the lines may be kinked. Use the access hole above the steering rack to check.
You also may have mixed up the fuel lines. Here's the flow path of the fuel: 1. Tank to pump. 2. Pump to passenger side fuel rail. 3. PS rail to DS rail. 4. DS rail to pressure regulator. 5. Regulator to tank. I'm assuming you've installed a fuel pump with one inlet/one outlet? Or was it the three port pump? |

Or was it the three port pump? I never pulled the tank to place it up front. To much work. I installed it on the firewall underneath the car. I was very careful to get the lines correct going from the 3 port to the 2 port fuel pump. One thing I did want to ask. My pump sets a little higher than my filter. So the flow goes in a diagonal from the tank line to the filter then to the pump. Does the pump use sucsion to pull gas from the tank to the filter and then to the pump and then onward. Because if it doesn't, then that could very well be my problem not getting gas. Here is a picture. Attached thumbnail(s) |
