So I suddenly can't start the Laurentian. I pour gas into carb and it starts..then dies. So I have no fuel. I got a brand new mechanical pump ($15! cheap). On removing the old pump, I noticed that even the main line in is dry dry dry. I drove it only a couple times before parking it. It's posdible I got pretty close to the bottom of the tank and sucked something up. I'm not sure though. Do these wagons have a natural flow to the pump or does the gas need to be sucked the length of the car? How can I diagnose it?
Thanks for any info.

Try blowing some air through the line from pump to tank should hear it in tank with cap off. If you don't hear bubbling in tank then it's EMPTY!!!! Fuel should 'free" flow thru line if rear of car raised up a bit if fuel level is that low, but with 1/4 tank of more should run to frt. easy. Make sure the F/pump push rod stays up to cam when installing the pump [ many different tricks for this]

Maybe it is out of gas........don't trust old fuel guages
Exactly. Another simple test ... tap on the tank from bottom to top and back again in intervals ... you'll know by ear if it is empty.

I would pour a couple gallons of gas in the tank so you know there's fuel. I put suction to the hose before the fuel pump, to make sure the fuel comes out. Don't use your mouth. Once I know the fuel comes out easy, I hook it up to the fuel pump.

If line is not pluged and the car has been sitting a long time I would put a filter between the tank and fuel pump. The fuel pump has 2 small rubber check valves in it and all it takes is 1 piece of rust to hold 1 of the check valves open causing pump to not work. If you have a vacuum gauge hook it up to output side of pump with line disconnected, get someone to crank motor and see if you get a preasure reading.

If you have access to a electric fuel pump maybe put a temporary rubber hose on the line going to the pump to see if it will draw fuel through the line?
