Gas Smell

garo1 · 08-05-2005, 03:53 PM

I recently had my truck in the shop for fuel filling issues along with other problems. The tank would spit gas back out whenever I tried to put gas in it, even though the tank was nearly empty. I had the tank replaced once and the last time it was in the vent valve was replaced. When I filled up this morning I got the same thing again, about 2 gallons of gas spilled out when I first tried to fill it and then it would finally let me fill it after 5 gallons or so was in the tank. Later this afternoon, when I got in my truck to leave go to lunch, there was a very strong gas smell in the truck. It's clear to me the tank isn't venting properly, but the gas smell is new since the Nissan engineer worked on it. Anyone have any ideas on what I can look for since Nissan is obviously lost?

I would send it back in. I had a problem with gas when the dumb mechanic didnt properly snap the fuel line back on and lost gas driving down the road. They may need to replace the whole gas tank and everything with it.

Go see the GM of the dealership and tell him to remburse you for lost gas and tell him what's going on.

Just checked out the manual and ran across this.

ON BOARD REFUELING VAPOR RECOVERY (ORVR)

From the beginning of refueling, the air and vapor inside the fuel tank go through refueling EVAP vapor cut valve and EVAP/ORVR line to the EVAP canister. The vapor is absorbed by the EVAP canister and the air is released to the atmosphere. When the refueling has reached the full level of the fuel tank, the refueling EVAP vapor cut valve is closed and refueling is stopped because of auto shut-off. The vapor which was absorbed by the EVAP canister is purged during driving.

The evaporative emission system is used to reduce hydrocarbons emitted into the atmosphere from the fuel system. This reduction of hydrocarbons is accomplished by activated charcoals in the EVAP canister. The fuel vapor in the sealed fuel tank is led into the EVAP canister which contains activated carbon and the vapor is stored there when the engine is not operating or when refueling to the fuel tank. The vapor in the EVAP canister is purged by the air through the purge line to the intake manifold when the engine is operating. EVAP canister purge volume control solenoid valve is controlled by ECM. When the engine operates, the flow rate of vapor controlled by EVAP canister purge volume control solenoid valve is proportionally regulated as the air flow increases. EVAP canister purge volume control solenoid valve also shuts off the vapor purge line during decelerating and idling.
