i am leaking diesel from my 2000 ford excursion, i have researched and find that the o ring eventually go bad/shrink from ulsd, in the drain valve behind the fuel bowl. and need to be replaced. i will do this, but i also have diesel coming from a half moon shaped hole that is in the pan that covers the torque converter. is this little hole supposed to be there? i was told it might be a drain for leaks so that the fluid doesnt end up going back into the system. need help quick!

 

Yes ....it is supposed to be there ....check this out
Welcome to guzzle's Ford PSD Maintenance Web Page

 

thanks for that info. i am working on the excursion today. hope to get the leaks taken care of. so, can you tell me the purpouse of that half moon shaped hole on the bottome of that pan?

 

Probably need to rebuild the fuel bowl.

The half moon thing is a heater for the fuel.

Check this out.

 

Thats a good vid you posted but removing the whole fuel bowl is very unnessesary. Just a waste of time. FBDV can be removed by itself easily.

 

Notice the video is called "how to remove and repair the fuel bowl"

So naturally, the video might also show how to remove it.

But its a lot easier to remove it, however if you dont want to be replacing sleeves every few months you can get it off with out removing the bowl. Its just a pain.
