Strong raw fuel smell.....

[Btheman]

I have a early 1999 F250 PS. With 206000+ miles on it. About two months ago, I started to smell a very strong odor of raw fuel. Started or not started. Does not blow much smoke. I have however noticed that it is using more oil and antifreeze.

What I'm needing to know is, what might be causing this? I have heard everything from, up-pipes, bad injectors. Any help on where to start would be great.

try replacing your fuel seperator valve assembly on the back of the fuel filter.

There are Many places you might have a fuel leak, don't replace anything until you confirm that's what's leaking

Climb up on the motor and look down into the valley with a strong flashlight. Is it "dry" Is there Engine oil or Fuel in there? How about on the back of the pass head where a hardline is clipped to it? Is there fuel leaking from there?

I'm not sure how losing (or burning) oil & coolant could be related to a "strong raw fuel smell". Check for leaks on all 3 though...

Check your coolant tank to see if you have fuel in your coolant. Leaking injector cups will cause the strong fuel smell as well

That's an excellent point!

It could be a common factor in the 3, never thought about the fuel smell "cooking" in the coolant.

Good Call Motomez!

Thanks Brother, I just had the same problem on my 7.3. I picked up a injector cup kit from Angelofishs on ebay for less than $400.

Happy New Year

I will check all those and let you know what I find out.
