I always use a handheld vacuum pump like a mity vac - about £20 on ebay. I've never had any luck with priming bulbs, then only seem to draw once fuel is in them.

If you still struggle to suck fuel through the pump, try drawing it from the pump feed initially.

Tip : raise the rear of the car as high as you can on jacks/axle stands so the height difference between the tank and the pump is reduced... better if fuel tank is full as well.
