Leaking Fuel
This is a 1996 F250 Powerstroke diesel issue (manual transmission, 4WD): I had just hooked up to a trailer when I noticed a spot under my truck... diesel fuel. I checked under the hood to find what looks like some sort of temperature sensor/relay unit dripping fuel while the motor is running. This unit has a brass-colored ring at the base and is found on the driver's side of the fuel-filter bowl. It looks like it is screwed in from the side with a connector at the end having two wires. This appeard to be where the drip was coming from. I have over-described this (I am obviously not a mechanic, but I am not afraid of most un-bolt and replace jobs). I do not have a parts manual so, can someone tell me what this unit is, and does it often fail in this way?

By that description, it sounds like the the fuel filter warning light sensor. In this case you can but a brass plug in it for now until you get to a dealer and can buy a new one. It just sets your fuel filter light on in the cab when it senses vacumm from the filter.

Many thanks for the quick reply... this site is the best (saved me lots of time and $ on my GPR issue - replaced with Stancor model and haven't looked back since). Does this fuel filter light relay often fail in this way (leaking fuel)?

It is the fuel filter restriction sensor (vacuum sensor), it is to tell you when your fuel filter is stopped up and you need to change it. With age they will start leaking. Most people do as carl said and remove it and put in a plug and just forget about replacing the sensor. If you do regular maintenance and change your fuel filter it will never be an issue.

Thanks for everyone's patience.... just one page back, same issue (DCATE posted 4/03) and a link to losssscause's photographic step x step. I guess the good news, is that the same things seem to go out about the same time, and the advice on this forum is good and consistent. Thanks again!
