During a brief January thaw my car suddenly died. Jumping the fuel pump
relay did nothing to get the car running again, and when the pump was jumpered I
couldn't hear the pump running.
Discussions on the PacNW928 mailing list revealed many "me-to's" with a note
from Louis Ott that the usual cause in later models was deterioration of the
hose connecting the in-tank fuel pump from it's fitting. The loose pieces
of rubber then get sucked into the external pump, causing it to lock up.
Sure enough, removal of the in-tank pump (pictured below) showed that the
in-tank pump had come completely loose from it's fitting.

Fuel pump exposed |

Removal of the cover exposes the fuel filter (top) and the external fuel pump (which appears dead). |

Fuel tank fitting |
|
After loosening the fuel tank cradle the fuel pump fitting is exposed. Tank has been mostly drained with a siphon pump and rear of car is jacked up. |

Fitting removed |

Well, as feared the hose connecting the internal fuel pump to the fitting has discintegrated. In addition, the two wires pulled loose from the fuel pump leaving the in-tank pump "dangling" in the opening. |

OK, now what |
|
Now I need to be REAL carefull not to push the pump into the tank where I won't be able to reach it! |

It's STUCK! |
|
Now I see why the wires pulled loose. There is something BLOCKING the bottom of the opening. Blurry picture, but it's the orange colored piece at the bottom of the opening. |

Finally removed. |
|
I pushed down the blockage with a screwdriver and finally pulled out the in-tank pump using a needle nosed pliers. Here's the pump and fitting with my watch for scale. Note that the rubber hose connecting the pump to the fitting is completely separated. |

Wonder where the extra pieces of hose went? |
|
I'd guess into the external fuel pump, which died VERY suddenly. |
