Diesel Smell While Running Air/Heater

[evilkracker]

First time posting here, but it seems like a good resource. Please bear with me. I bought an 06 F250 and have nothing but problems with it. Recently, I have a strong diesel smell in the cab when running either the air or heater. When it first started, it was subtle. It seems to be getting worse to the point I have to turn off the air. Haven't found anything in the forums for this, so if you know of a previous post and can post it, I would be more than appreciative.

Thanks in advance for your help!

Probably the up pipe from the exhaust manifolds to the turbo is cracked.

Check for fuel leak around the engine mounted fuel filter. See a lot of pres. reg. gaskets and or filter cap leaking.

Have you had the filter changed any leaks around the filter cap or the reg spring housing and fuel on the ground is it fuel or diesel smoke how many miles on it just serviced just a little short on info.

I had the filter changed about 6 months ago, but didn't even think to check for leaks around there. I will check and let you guys know. Thanks for the help.

X2 on checking the fuel filter cap, I had a similar issue a while back
and all it was is the "O" ring on the fuel filter cap.
