Drove my 914 to a PCA function yesterday morning, 93f and humid.
After driving on the interstate at 70-75mph for around 45 miles I exited and the motor died. I had enough momentum and coasted into a gas station/convenience store where I topped off the tank and tried to restart the car, no luck. The car would fire, run a few seconds and die then refused to re-start for another 10-15 minutes then the same scenario again. No tools to diagnose or repair. While waiting on AAA for three hours (another story) I would occasionally try to start the car with the same results. Today, car started normally, runs normally. 1974 L-jet, original three bung fuel pump, original location. 500 miles on new tank, sock, filter, ss lines. |

Yep, sounds like vapor lock to me. I have mine all in the original locations and wrapped it in high quality heat wrap. Haven't had a problem since. I can tell it still thins out when I park it on a day like you describe but it starts up and goes fine after 5 seconds of pushing new fuel. Before the heat wrap there was nothing I could do but wait.
I was racing today on black tarmac 90 degrees, started up all day under extreme conditions. Is it design engineering? I can't remember but everyone uses it. |
