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. |

Had recurring vapor lock in my 74 1.8 L-Jet in the early years even with regular fuel.
Wrapped the lines in insulation, which reduced frequency of incidents but when it did happen the condition lasted longer as insulation kept heat IN! Moved pump and filter to front, as much to address that as well as the bad fire hazard having all those lines and connections right over this hot pipes. Funny though that yours cut off at exit while running. A clue? These folks have great ideas. Our cars, maybe particularly the 1.8s, do not like hot, humid driving weather. At my age, now neither do I. My second solution is to keep it parked on such days. (IMG:style_emoticons/default/beerchug.gif) |
