  1. Does it actually pull gas though? Your red primer bulb has a whole right in the middle of it. I have the same spare cuz mine tore as well, so I put the new one in that's exactly like your red one with the whole in the center and it doesn't work. It doesn't pull gas when I prime it. My other one was a smooth surface with no whole on the bulb. I don't know why it comes with a whole, it makes no sense. Does yours work for real? If so, how to you press it? Lol
