Alert me when someone posts in this thread:

Wow. Dual Webers!

So there's a couple places to look.

1. The fuel pump. The old OEM style mechanical pump has a screen filter you can access by taking out the little screw on the side. I've had those clog up with rust from the tank. Can't imagine you have that type of a pump with dual Webers! Often, electric pumps have a filter right before them. I have electric in a couple of my Saabs, under the rear seat, and always put a filter before them. So find your pump and see if there's a filter before it.
2. The tank itself can get clogged at the outlet. To check this, remove the fuel line as on the tank side of the pump and blow some air down the line. You should hear some gurgling pretty quickly. Remove the fuel cap first- go easy on the air pressure- 10 psi is plenty- or you'll have gas all over! (how do i know this?)
3. Less likely, is the fuel vent itself. IE, it could be that the fuel tank vent is clogged or pinched and the pump can't pull fuel because of it. You check this by loosening the gas cap and trying the car. Maybe try this as step 1. I had a car with this problem and the symptoms were that it would start and run in the morning, but only go a couple of miles and die. Loosen the cap and you heard a "whoosh" and you could drive a couple of more miles.

Now there are little screen filters on the carb inlet on some carbs that can get clogged up. But you said that there's no fuel at the filter, so that sorta rules that out.

And of course you know that the fuel filter will not be FULL, right? At any given time it's around 1/4 full on my VSaabs.

PS: Saab guru Jack Lawrence says to NEVER use a plastic fuel filter under the hood. Too dangerous! And of course, that's what most of us use...
