I replaced the fuel pump with a new one and the bus does the same thing....

Get this I swapped the SVDA dizzy (running the compufire timed at 7 BTDC) with 
the original running points and both hoses connected and I rode around the 
block and the hesitation is good.... I'm going on a longer ride in about 45 
minutes to further investigate... 

I'm thinking maybe the SVDA was losing vacuum somehow ( sounds like I know what 
I am doing)

Stay tuned...

  I pulled the fuel line off the carb and ran a line from the fuel pump to a 
jar and started the bus and there is a nice stream of gas coming out of the 
fuel pump which makes me think that it's ok, might be a little low (2.5 psi) 
but I was looking to see if it;s was trickling out of the pump..(looking to see 
if  it was clogged up)

  Now I'm wondering what to do next.......

        2.5 psi should be enough if there is enough volume.You just need enough 
fuel to keep the float bowl full while driving.

      I checked my fuel pressure and it read 2.5 psi.... it did not move at all 
when I revved the engine....this is on a 1600DP stock engine.... 

      It's lower than the Bentley specs which are between 3.0 and 5.0 psi.... 

      Suggestions? 

      BTW, this is the original fuel pump in my 71 Westy. I did pop the top off 
about a month and cleaned the screen in it.
