Smell of Diesel

[-Grumpy-]

I have a 2014 Itasca Meridian 40U. Every once in a great while, if the fuel tank is near 3/4 or more and I am driving on a roller coaster road or making a lot of turns, I start getting a strong smell of diesel in the cab even with the A/C switch on MAX Air, which is supposed to recycle inside air.

It takes about 20 minutes for the smell to dissipate even if I turn the exhaust fan on while driving.

Anyone else having a similar problem?

Rick,
Just wondering, are you getting a smell of "liquid" diesel or, "Exhaust" smell of diesel?

It is definitely the smell of diesel and not exhaust.

Source might be one or more of several items. Fuel cap faulty, flexible connector at fuel tank/fill point loose or cracked, flex fuel line leaking, etc.
I suggest crawling underneath with a bright light and look for any wet spots near the fuel tank and all lines.
