I have a fuel leak on my 2000 Ex, 7.3l. I'm guessing it is at the fuel bowl. I replaced the drain valve o-rings about 5 years ago. Would you guys suggest I purchase a kit to replace all of the fuel bowl o rings and seals or just do the drain valve o ring again? The truck has 210k miles on it.

 

It's usually just the drain valve that leaks, but it certainly wouldn't hurt to change all of the o-rings. It isn't a hard or particularly time consuming job anyhow. If it is indeed the valve, you might be able to stop it temporarily by snugging up the four torx screws that hold it on.

 

Everything our little electric friend said above me is true. Its usually the drain valve, but I would do the whole thing, time permitting.

 

Thanks guys. I will order the bowl rebuild kit and take it from there. If I remember correctly, it was a fairly simple job to do the drain valve o-rings. I'm sure doing the rest of them won't be a big deal. Last time I had to do them it was in the middle of the winter, no garage. At least the weather is more agreeable now

 

I've got a video outlining it on YouTube of you find that will make it easier.

 

Thanks for the heads up on your videos. I will check them out.
