<VV> Electric pump stopped feeding gas to the carbs

[AeroNed at aol.com]

Stephen,
 
My one Corvair with an electric fuel pump has the pump mounted behind the  
rear seat, opposite the heater unit. I have run that set up for about 10 
years  and the accompanying conditions over that time. I've also run the tank 
"dry" on  purpose with the pump. Even though I live in Kansas, I've driven 
the car all  over this beautiful and sometimes hilly country. Anyhow, the 
purpose of my story  is that I've never encountered a fuel pump related problem.
 
If you need more evidence, nearly every front engine aftermarket  
installation of an electric fuel is at the opposite end of the vehicle from the  gas 
tank. The reason modern cars have the fuel pump located in the gas tank is  
simplicity and cost. The sender and fuel pump are now one assembly.
 
If the fuel line, rubber and/or metal, between the pump and the tank are  
good the pump will work as advertised. After all as far as the fuel is 
concerned  the electric pump operates just like the mechanical pump.

I kept  trying to figure out why my pump kept pumping but stopped  
feeding  gas to the carbs yesterday after running well at highway  
speeds for  over 50 miles.  Was just corresponding with a forum member  
when  I had a lightbulb moment.  When I parked the car, the tank was   
facing downhill and only had about a 1/5 of a tank left.  Perhaps  the  
feeder line from the tank was exposed to air in the tank and the  pump  
sucked up the air into the gas line... thoughts?  I  usually don't let  
it get below 1/2 full, but since I'm trying to  drain it, I let it get  
low this time.

Perhaps two or three  more weeks before I have the time to move the  
pump to the front  although if this was the cause of the malfunction,  
having it in  front wouldn't have made a difference.
