1992 W250 fuel leak

Dec 10, 2006 4 Replies

I'm leaking fuel from above the heater element that sets above the fuel filter, has anyone removed this heater before. The only thing I see that holds it on is the shaft that the filter attaches to and it is slotted, I just don't want to torque on something if there is more to the removal.



Thanks Chris

Disregard, I figured it out..... Chris

Well, tell us what you found, please. So we will know what to look for when it's our turn.

Sorry about that, I'm new to this newsgroup posting. There is a rubber seal that sets above the fuel heater that the fuel fitter attaches to. To replace, remove your fuel filter then using a wide blade screwdriver remove the threaded insert that the fuel filter attaches to, the heater will drop down, swap out the gasket ($1.90) and snug it back up. I probably wasted $20 in fuel putting off the repair for a 20 minute job. My seal was completely flat and hard so I would imagine most folks are by now, I bought the truck new and change the fuel filter every 15k or so, I will make sure to resnug this everytime from now on.

Thank you, that's good to know. I am much the same way, lose money putting off a 10 minute job.
