<VV> Question or two..

[Kerry B]

Hi,

My car, when driving at 55 and up, at times will simply shut down. I 
usually have warning that this may happen because the car will act like 
it's starved for gas when taking off.  Pulling over to the side of the 
road, activating the back-up electric fuel pump will get the car started 
again. (car has both an inline backup electric pump and the usual 
mechanical pump. Mechanical pump is new last fall.) Problem seems to 
occure after driving for some time, though it was not hot out yesterday 
so not sure if it can be a vapor lock. 

I am not sure how to go about proving what the problem is. Am thinking 
maybe an air leak in a fuel line. (though I haven't found any evidence 
of a leak yet.)  Can the fuel pump rod be worn? (if so can it be removed 
without disassembling part of the engine?

The electric fuel pump is  located behind the front cross member.  Gas 
tank was replaced a few years ago. How should the gas tank vent? (I am 
assuming that air needs to get into it as the fuel level drops??) Could 
something be blocked? Has a new fuel filter.

Car: 1964 Turbo. Convertible...
