1974 2056 D-Jet. Fuel pump mounted on firewall in engine bay. A few times over the summer, I experienced vapor lock and plan to move the pump the front of the car this winter. Fuel filter replaced last year and tank is squeaky clean.
Drove 454 miles to Okteenerfest. Stopped for lunch yesterday, it was hot. Fuel pump vapor locked. Waited it out, got back on the road and made it to Banner Elk. The drive today started off fine...probably went 70 miles or so with no problems before vapor lock set in. A guy at a golf course gave us a spray bottle of water. We sprayed down the pump, car started and we were on our way. After that, the pump locked up three more times in a span of about 20 miles (even after a two hour lunch break). Each time, the water spray cooled the pump down enough to get the car started again. Our luck was going to run out at some point having a place to pull off, so we cut the drive short and headed back to the hotel. Other than moving the pump to the front, what's the solution to get me through the weekend and get me home? I'm in a great place to be having this problem, but wanted to poll the world for additional advice. Thanks in advance! |

Thank you for the responses. I can't wait to move the fuel pump up front and be done with this problem. It was a little scary having the engine die on the mountain passes today. (IMG:style_emoticons/default/dry.gif) I spoke with D-jet experts Lewis and Clay here at the event. They confirmed my fuel pump is fine...it's vapor lock.
I've never had a problem while moving on the highway, regardless of how hot it is. The driving portion of the event is done and it's almost all highway miles home...where airflow will keep it cool enough. Clay came up with the simplest overall temporary solution that only involved a quick trip to Lowes. If I get vapor locked, turn a can of this upside down and spray the fuel pump to freeze it: |
