<VV> Frustrating problem

[Geoffrey A Johnson]

Pump rod on the fuel pump worn to much?  This happened last week on my 
63.  Old pushrod was worn enough that it wwould work for a good drive 
then once hot would not run at low speeds.  Would do highway speeds but on 
slowdown  it 
would die.  Measured it and pump rod was a good 3 millimeters shorter 
then a new one.  Swapped it out and now it runs perfectly.  Figure it was 
enough to get enough fuel at high RPMS but with heat was to weak to work 
at lower rpms. 

Just a thought...
