Why does my truck emit an odor when making a turn

[mexicanjoe]

Ok group this one is for the books: My '89 F-250 has this nasty habit of running great in town and when the a/c is one its very comfortable. However when I make a turn, either left of right, I smell the odor of raw diesel! What gives? I don't think my fuel tanks are loose. What can you guys proffer this confused driver?

Does it make a difference with the fuel tanks full or low?

When my fuel heater was leaking I noticed the same thing happening, I would only smell diesel when making a turn. It was the strangest thing, I never could see any fresh diesel on the connector, but I stopped smelling diesel after the problem was fixed so obviously that was the culprit. Do you see any damp spots on your fuel filter housing or return line caps?

I WAS going to say that the reason I emit an odor when I make a turn, is just because I am getting older.

Then I decided not to say that. Because you were looking for a real answer.

Aren't you glad I didn't say that?

bbjordan, it doesn't make a difference how full the tanks are. its really strong it I pull outside air when using the a/c. When set on MAX it doesn't emit the raw fuel odor. As far as my heater: I placed a small paper towel under it and drove it for two days. when I checked it . it was slightly stained ; not very much

I was thinking it might be a leaky gasket between the tank and the fuel sending unit, but after reading more, I think Golden Helmet might be on the right track. It's probably something under the hood.

It's going to be under the hood, look on the passenger's side(because that's where the cabin intake air comes from)..
