I started tinkering with my project again a few days ago, and am in the process of getting the engine bay back together. Only problem so far is I had to replace the right engine shelf, and I cant remember how the fuel pump mounts ! I attached a pic of the area where the Haynes manual shows it to be, but the pic in the manual isn't the greatest. Also in the pic, what mounts in the slotted J shaped bracked above the motor mount? It has been too long ago since I tore this thing apart and I screwed up and didn't take enough pictures !!!!!! TIA

In a properly maintained car you should not experience vapor lock. I suspect that Porsche relocated the fuel pump because they couldn't count on people properly maintaining their cars. In the back it is close to a source of heat and possible ignition for those cars that owners maintain poorly.
At the pressure in an EFI system vapor lock shouldn't occur with a properly maintained vehicle. It is easy enough to relocate if you have the proper mount but a pain to replace it and the fuel filter. That said, mine is up front. But it came that way... |

My brand new (~1000 miles) '73 1.7 had serious vapor lock problems in 80 degree weather in the mountains of Colorado. When I finally got it back to the dealer they said, "yeah, we know about this, we'll fix it up." Unfortunately, I don't know what the remedy was, but it worked - never had a problem again.
