Don't know about the Mustang, but on the Lumina I'm junking due to engine failure, I put a new gas tank in last year. Swapped in the old pump that had 180k miles on it. I figured the Lumina was good for about 3 more years until rust would make it a real eyesore, and I'd have wet carpets.. OE pumps on that runs $250. I play helper for my son, and we both figured it wouldn't be hard to replace the pump if need be. The first time dropping the tank is the hard one. Then you know the best method, connectors, etc. Thanks twk, for the silicone vs WD-40 advice. But on more thought I think I'll just wrap my parts in Saran wrap dry. Should be enough to keep rust away. I don't think you can do anything to keep seals from aging, or at least it's not something I'm inclined to worry about. New parts for old cars is par for the course. |

Wrap it in a plastic bag and put it in a box. Then hope that in 10 or 15 years, the next time you need a fuel pump, you have a car that takes the same one that you wrapped in plastic and put in a box. You can get the longest life out of your fuel pump by keeping the gas tank full. Gasoline acts as a heat sink, so if the tank runs to E and you put in five-bucks, whatever, just to hold you till tomorrow, then tomorrow do the same thing, and keep the tank near E most of the time, then there is no gasoline to act as a heat sink, and the pump motor runs hot which shortens its life. Keep the tank filled more than driving around with it empty, and you will have a fuel pump that lasts almost as long as the car. |

The idea of spraying the pump with a lubricant is okay, I suppose. But WD-40 is the worst stuff you will ever find for this. WD-40 is great to free sticky mechanisms, but you must wash it off once the mechanism is freed. WD-40 has a component that when everything else evaporates/dries up, turns to goo that will glue stuff shut so tightly that a fresh shot of WD-40 might not be able to free it. |

That means there must be brushes and slip rings. I have always wondered how sparking does not ignite the fuel. Perhaps all is OK if the pump is totally submerged, but how about if you are running out of fuel. How do you prevent the pump from igniting the gas in the tank? |

"silicone spray" you buy at the automotive store or supermarket is mostly petroleum distillate - i.e. mostly stuff like wd40. the percentage of silicone is minimal. 2. silicone in fuel will quickly screw up oxygen sensors. on both counts, either don't bother with anything, or just use wd40. it's not like it turns into cosmoline. -- fact check required |

[and why "cooling" is considered so important is a complete mystery. windshield wiper motors can run indefinitely "uncooled".] -- fact check required |

I did say a "good grade" of silicon oil. Maybe I should have said a high percentage of silicone. I have a 100% silicone oil spray on my shelf right now. It was about 3x the price of WD-40 and well worth it. 2. I also didn't mean to flood the pump with the entire contents of the can. A light coating inside and out should protect the pump nicely. Hardly enough to damage any sensor. Something covered in WD-40 and wrapped in plastic, will get gummy in a couple of months time. No doubt about it. -- For all you know this message was...

Some cars have a float check too. I know someone with an 86 Grand National and with a 1/4 tank backed down a loading ramp so no one could park close enough to ding it. Wouldn't start when he got back. Pulled it out level and it fired right off. |
