Re: CJ carb out of gas after it sits?
 

You have to prime the carb to get the gas running again. The line has
been air locked by the filter being in wrong.

Prime it, get it running, 'then' shut it off and see if it drains back.

It is already drained now. Playing with it is a waste of time and money
until you test it after you have 'fixed' the problem like you did by
moving the filter.

I for one have seen your problem 'tons' of times and not once has it
been a bad fuel pump, not once.

Re: CJ carb out of gas after it sits?
 

Turned out it was a bad fuel pump after all, but not the way you might
think. It appears the plunger is jammed (or at least loose from the lever
arm), because when I took it out and moved the lever manually, the plunger
rod didn't move. Never saw or heard of this before.

New pump fxed it right up. Fuel filter is also now properly oriented as
Mike says.

Side benefit is while I was in there I noticed a vacuum leak I hadn't caught
before and this really smoothed the idle.

thanks, guys, for all the advice.

Re: CJ carb out of gas after it sits?
 

FWIW, My '76 alweays does this if it sits for more than 12 hours. I have to
crank it for about 5 seconds, then it styarts & runs fine. I've always
assumed fuel was venting from the bowl and evaporating. It did this with the
original Carter 1bbl carb and old fuel pump, still does it with a Webber
2bbl and new fuel pump & filter.

Well after suffering this same problem and following this thread, I decided
to go ahead and spend the $15.00 for a new fuel pump. Well it fixed my
problem. I can let the Jeep sit for two days now and it cranks on the
first bump of the key. Before the new pump, after sitting for a day or
more, I would have to crank on the damn thing for 20-30 seconds.
