Wow! No sooner had I read emrydc8's comment, then driving I smell gas.
I look and the 2" piece of hose between the fuel damper and the pump was POURING fuel, I lost probably a two litres. I was able to catch one... Good thing I had an available shop with lift!

new hose fixed in an hour.
if this hose was seeping for a while, could the pump suck in air via the cracks in that hose?
If that hose had completely broken, as I was driving, it easily would have cost me THOUSANDS of dollars. Not to repair, but for all the other things that would happen.
First of all, there would be no stopping 90 litres of Vpower from going directly to the ground ($120), but the cost of the call to the FD to handle the spill ($975 call out fee), a municipal pollution fine of $3500 - $5000. and because it's a 2" piece of hose that would have failed, my insurance would not have covered it.....
