I've been hunting fueling problems with my R32 for a while and have found the culprit - a faulty Aeromotive in-tank pump.
However, one of the things I was considering could have been an issue was the pressure in the fuel tank itself. When I open the filler cap there's a very strong outrush of air - sounds like truck air brakes. Enough to push fuel out of the return side at the fuel rail with significant force if I remove the hose. I'm wondering if this is right, I thought the tank should be vented to prevent this?

all fuel tanks have a breather pipe to stop that as too much and the tank implodes but it will still do it if the tank is nearly empty

The tank is pressurised in stock form so unless a massive amount off air is released when opening your tank, don't worry about it, it's supposed to woosh for a second or 2 when opening the petrolcap ;)

Interesting. What pressurises the tank? If anything, with the fuel being pumped out, I would have expected a vacuum in there.
