Fuel Odor
'98 4x4 Ranger XLT. A few months ago i got an P0455 OBD-II code (evap system leak). For a while I've noticed a fuel odor which seem to be coming from the fuel tank area. It smells strongest between the cab and the bed. Anyone else ever have this problem? Just wondering what I might be getting into before dropping the tank or moving the bed.

Stuck my nose in the fuel door, no odor at all. Odor seems to be coming from the tank area. The smell is strong in the space between the cab and bed. I checked for fuel leaks and the tank and lines are dry.

Continuous Memory Diagnostic Trouble Code (DTC) P0455 indicates that the Evaporative Emission (EVAP) control system detected a large leak or no purge flow.
POSSIBLE CAUSES:
- After market parts and accessories nonconforming to the EVAP system specifications.
- Damaged, missing or improperly installed fuel filler cap.
- Blockage in fuel vapor hoses/tubes (EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube) in EVAP system.
- Disconnected or cracked fuel vapor hoses/tubes in EVAP system.
- EVAP canister purge valve stuck closed.
- Canister vent (CV) solenoid stuck open.
- Fuel tank pressure (FTP) sensor malfunction.
- EVAP canister leaking.
- Fuel vapor control valve tube assembly blocked.
- Fuel vapor vent valve assembly blocked.
ACTION:
- Check for missing fuel filler cap. If the cap is loose DO NOT DISTURB EVAP system.
- Verify that both the input port vacuum hose and EVAP return tube are attached to the EVAP canister purge valve.
- Verify that the CV solenoid is properly seated on the EVAP canister (if possible).
- Visually inspect for disconnected or cracked fuel vapor hoses/tubes between the intake manifold, the EVAP canister purge valve, the EVAP canister, the fuel vapor vent valve assembly and if applicable the fuel vapor control valve tube assembly.
- Check for damage to the fuel filler pipe and the fuel tank.
Also, look up the P0455 code here, it lists some things to consider: OBD-II Trouble Codes
And this thread has some relevent information on the EVAP system, as well: EVAP Thread
