What is this part called?

[str8razor]

Can anyone tell me exactly what the pressure switch or sensor with the single red wire going to it is called? I went to Autozone and they couldn't locate it in their computer. He pulled up a fuel and oil pressure sensor but it had 3 prongs on it while this one has only one connector on it. Any replies will be greatly appreciated.

Thanks

That's the water in fuel sensor. It's not really needed. Sometimes when they get old they start to leak fuel. You can take it off and plug the hole with an 1/8 npt plug.

Thanks Sgt Dave! That's exactly why I'm asking. This thing is leaking like crazy. I'm off to Autozone again!

Thanks a bunch!

Your welcome. Id be surprised if autozone carries that sensor. You'd be better off going to the hardware store and buying the plug.

I thought that is the fuel bowl restriction sensor? p/n E8TZ-9S283-A

Thats what it is, couldn't remember what exactly it was called. I replaced one on my dad's truck.

The only reason I knew was I just replaced the damned thing on my truck. It actually was leaking through the electrical wire.

A brass plug is cheaper than a sensor you can do without.

Whatever it was, there's a brass plug in it's place now and the truck runs fine without it. LOL!

A little FYI on the subject. Since there seems to be a conflict between it being called a water in fuel sensor or a fuel filter restriction sensor, I may be able to shed some light on it in case anyone is not aware of the following. Most diesel fuel filters are designed to swell up if they get wet with water so they do no allow fuel to pass through them. With that said, I can see where it is called both. If I had to guess, I would be willing to bet, it senses the pressure on the output side of the filter and only knows if there is not enough fuel being allowed to come through the filter. In other words, it works in either case; If water has it swelled up enough not allowing fuel to pass through it or trash has restricted fuel from passing through it.

Any way, thanks for everyones replies! I have it plugged off for the time being, but will order one from NAPA this week.

Thanks!
