Smells problem
1986 Jaguar XJ6 6 cyl Front Wheel Drive Automatic 150k miles

Actually, my girfriend was the first to notice the smell of gas fumes on my clothes before I knew anything about it. That has been since 2000; I bought the care in 1998 or 99.

Sometimes the smell is stronger when I fill up. Other times, it is isn't as strong. But it is there. One day recently, I thought it was greater when the right tank was only filled.

I have had the switch over valve replaced, both the internal and the external ones.

I don't recall if the fuel pumps were changed.

Gas tanks are not leaking; in fact, I had one of the tanks replaced in 1999. But I don't remember the smells, more accurately, my girlfriend didn't complain about the smell then. New seals for the gas caps/covers were put in around 2002 but that didn't help.

When the hit 150 K, I replaced the engine in 2006 with a Chevy remanufactured because I was tired ot the rope seals leaking every other year or so and spending the money to get them replaced. At that time I also got a remanufactured transmission and new exhaust system. I have 20 K on the new engine. But the smell still exists.

Otherwise, the car is in pristine condition. My mechanic keeps it running smoothly; no other problems.

But my girlfriend has now alerted me often enough so, I am now sensitized to the smell and it is particularly strong when I open up the driver side window; I feel nauseated. Yes, the smell remains on my hospital scrubs and my dress clothes; so I guess others can smell it, too, but they haven't embarrassed me.

The body is in good shape. When the floor rusted out I replaced that but the smell still existed. My trunk floor has no rust or cancer. My mechanic who is around fumes all day really couldn't smell it, thinks maybe it is my car door not sealing properly. I don't know.

Any ideas?

The fuel evaporation system is designed to keep fuel and crankcase vapors from escaping into the atmosphere. The system consists of a fuel tank (2 on XJ6) with expansion space, solenoid operated purge control valve, vapor separator(s), pressure relief valve, restrictor, canister, and connecting lines and hoses.
Fig. 1: Fuel Evaporation System (XJ6)
When the fuel tank vapor pressure exceeds a pre-set limit, the pressure relief valve opens and vapors flow into canister for storage. The pressure relief valve also allows air to enter the tank when vacuum exceeds a pre-set limit. On the XJS HE models, the pressure relief valve is set to open at 2 psi.
When the engine is warming up on XJ6 models, the purge hose is shut off by an energized solenoid valve. After engine coolant temperature exceeds 113 F (45 C), the valve opens since current no longer passes through a thermal switch (also part of air injection system on Federal models).
When the engine is warming up on XJS HE models, a timer/relay switch delays purge valve opening for 45 seconds after engine is started. This delay allows catalytic converters to warm up to efficient operating temperature.
On both the XJ6 and XJS HE models, the purge line restrictor limits maximum purge air flow rate.
