Okay, I found this post because I have the fuel smell and a drip off of the engine. This is my step-dads truck. He had the leak appear last year about this time and it sealed up after a few hours and he hasn't seen it since then. That is what prompted me to start looking for a solution I changed the o-rings out this evening. Has anyone continued to have a drip after the fact, possibly from residual fuel on the valley still dripping down?

My drip is coming off of the dust cover. There is a little dimple on the very center of the dust cover that it seems like it is dripping out from.

I have fuel all over the valley and then this drip. Does this sound like the same issue? Have others had this drip from the same location? I think I read all but one page of this post. I probably skipped the page that says if your drip is off of the dust cover it is a different issue!

My next course of action is to check/change the WIF sensor o-rings.

Thanks for the help.

Jeff

Anyone have a set they want to sell me for cheap? I was thinking about changing my fuel filter so I might as well do this at the same time.

With nice weather yesterday, I finally got around to doing this o-ring fix [fortunately, hadn't needed the truck recently ....]. As noted, the process is straightforward, but the space is so cramped that its a pain in the arse to unscrew the T20 torx screws and remove the valve. I couldn't find a 1/4 drive T20 socket closeby, so I ended up using one of those cheap 90 degree angled T20 key [like a hex key]. I don't have real big hands, but it was tough to fit back in there, especially spread-eagled over th engine and reaching down behind the filter. Ended up dropping the key, and one of T20 screws, down into the valley multiple times [requiring a second trip to the local Advance Auto for one of those flexible recovery grippers]. Ended up taking a couple hours, what with the trips to Advance, so be prepared. I had previously installed a drain line on the purge outlet, so I avoided any more diesel mess. As expected, this fixed the leak!

Maybe someone replaced them. The 94-97 fuel bowl I messed with had torx head screws. :shrug03:

most likely they are metric...most of my hpop and fuel bowl bolts were.
I droped one of my thermostat bolts when i added a 203 t-stat.. disapeared into no mans land..i just added another from the local store..ended up swaping all of them since the other two now had a different size head...

I'm not sure on your 2000 but it should point to the passenger side to drain. If it doesn't even with the lid cracked open try it with the engine running.
