I have been smelling gas fumes from my 90 YJ wrangler 4.2 L engine.
Since I don't see any visible leaks anywhere, I suspect maybe the
charcoal vapor canister may have died. The only problem is that
chryslerparts.com says their system shows that this part is no longer
available and no dealer inventory was found. Any ideas for a source for
this thing. Could it possibly be just the replaceable filter element
causing the problem.

I took a charcoal vapor canister apart once, dried out the charcoal inside,
and glued it all back together. They aren't designed to come apart, but
they do. Everything seemed to work properly when I was done. I suspect a
leak or other malfunction in your case though.

If your canister is blocked or saturated, the engine will act like it's
out of gas.

It is much more common to have a leak on the suction side of the fuel
pump which would make hard first of the day starts or to have a leak in
the return line which makes for smell now and then.

Because the return line isn't always full, the leak can be hard to
spot. I look for stains on the lines, usually where the rubber hoses
join or on the clips that hold the lines to the frame.

The YJ also has a rollover check valve with a mess of hoses up under the
back fender. This is a common spot for leaks and fumes.

Aloha all
There has been some new developments. It seems that now the Jeep is very
hard to start (requires much cranking) after it has been driven and then
sits for a while. When it starts it runs very rough and the gas smell is
strong. Seems like it was flooded. It doesn't seem to matter if the
throttle is open or closed. It has always been a bit hard to start when
hot after driving, but nothing like this.

99% of the time it starts fine at first morning start. But once in a
while it will start but runs very rough for a few seconds.

Driving is all fine. I have checked the choke and the choke heater. All
seem to be working fine. Could a bad choke unloader be doing anything to
cause the bad initial morning start.

My suspicions have switched to a bad float or float valve possibly
causing the flooding and gas smell...at least for the warm start problem.

Any more thoughts?

By the way, this is a new computer and I haven't yet figured out why it
thinks my name is remove. Sorry about that.
Aloha
Joe in Maui
