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. |

I had a leak develop under the fuel tank. Pulled the tank, changed the lines and put it back in. I took it for a drive and it was fine until it died. I stayed near home so I pushed it back and pulled the tank again. When it got warm the fuel line kinked and cut off the fuel. You waited for 3 hours for AAA, I don't think I've ever had vapor lock last that long after the car was off

I pulled the fuel pump (for the fourth time) and noticed no fuel was coming from the supply line. The 9mm line underneath the tank was kinked. Shortened the hoses to remove the loops and all is well. I feel like an idiot for not examining those hoses more carefully. |
