Fuel smell in the cab

[topcop45]

Within the last two weeks I have been getting a strong odor of diesel fuel inside the truck (2006 CCSB). I opened the hood and checked for any leaks and could not find any. Any ideas?

Thanks in advance

Look at your firewall for black soot. May have to get under the truck and look up from the bottom. Pretty common for the flex joint on the up pipe to crack and cause the smell.

If you don't see anything looking at the pump or lines, look at your tank mine started seeping a little if I top off and will run down the tank.

Changed your filter lately? Filter cap seeping?

Throwing out some thoughts.....

Thanks for the advice. I'll check all those!
