Bob,
If you want spares here are some photos of this Pulsar 1
aircraft that came from UAE without Import Permits and Documentation,
which you might pick up for a song. I don't know where ealse you will
find spares.

Hi,=0A=0AEnjoy Saudi Arabia! And have fun in Bahrain F1 race! I have been c
ouple of times in Damman.=0A=0A=0AIt was a good race, watch it from Speed c
hannel. You need to be next to the race track to understand how fast those
cars accelerate and stop when they get to the corners. They get 1 G just wh
en you release gas pedal and up to 4 G when you slam your brakes. When you
do that 2 h I am not surprised that you are exhausted!=0A=0ABR,=0AEsa=0A=0A

No, pump was horizontal. There is no check valve in the pump. I can
blow thru from both directions after removing the pump.
The pump and section of vent line are going to the NTSB tomorrow.
I figure the fuel burn at about 1 oz per minute.
Or 4 oz out of a 9.5 gallon tank.
Or 4oz out of the empty space of 4 gallons.
How much vacuum would removing 4 oz from 4 gallons cause?
When I get done with NTSB, FAA, Insurance I will post pictures.
Found extensive damage in the foot well today.
