No Water-in-Fuel sensor?

[realfstkid]

Hey guys,

So I was tooling around my truck, since it's not working and all, looking for anything suspicious, draining my fuel/water separator to see if there was excessive water in there, anything...

Anyhoo, I came across a plug that was unplugged (and looked like it had been for a while) but I couldn't find where it came from. Checking the service manual, the plug comes from the "water in fuel sensor", however said sensor seems to be absent from my fuel filter / separator / pump housing. Is this normal? Aftermarket part?

Here are some pics:

That is interesting. The three connections are for the water in fuel sensor, fuel heater and fuel pump. I think anyway. I don't know which is which. I'll repost if I find out later tonight.

Some of the later models didn't have a fuel heater. I don't remember for sure when they took it away. But I do know that if you had the fuel pump assembly replaced as a whole housing there will be no fuel heater. The water in fuel plug is the black one closest to the drain plug. The third connector is the fuel pump connector.

Wow. So the assembly isn't available with the heater at all? I don't really need one but what about the folks in the cold areas of the country.

I asked about that when i took the 6.4 class and discovered that they hadn't been putting them in the 6.0 for a couple of years. And i think it went something to the tune of when the motor is operating the fuel that is being returned is heating up the fuel in the tank enough plus that is why if it's cold enough to gel the owner is supposed to be running anti-gel additive. Don't remember 100% for sure.

That makes a certain amount of sense. Thanks for info!!!
