Brand new to the 914 world. My car, a 74 2.0 was parked for 25 years, bought as a roller. Now missing the fuel pump( among other stuff) looks like it was plumbed for a 2 port pump anyway as 1 line to the injectors with a return line only at the end of the run, no y connector. I plan to replace all of the fuel lines so now is the time to place the pump. Seems real easy to place on firewall as lots of room there. I have read countless articles but not much recent stuff and most are vague with instructions assuming I have full comprehension of the car, which I don't. It sounds like stainless lines in the tunnel are a must, what fuel pump is suggested? Front or rear?,modify and put in tank?? Suggestions or point me to a current article. Any help really appreciated.

All ready to order new stainless fuel lines for the tunnel and after talking to Auto Atlanta they suggest not replacing the lines in the tunnel as they are not prone to failure. Any thoughts? I had planned on replacing all of the fuel lines.

Not someplace I want to be. They are almost 50 year old plastic not designed to hold the pressure of the Fuel Injection system, just the weight of the fuel in the tank. If you move the pump up front you are now running high pressure fuel through the plastic line. Does AA even sell the SS lines? Jim |

Jim Several older mechanics from Europe who have worked on 914s for many years have told me that the plastic fuel lines are bullet proof. Go figure. The added pressure may be an issue. BTW, it's advice, not advise. |
