It lay any way, just pump it vertical

I don't worry about how mine lays and it seems to be fine , it mostly stays on its side best I can tell

If there are no leaks, it makes no difference how it's turned. If the bowl on your carburetor is not filled enough it will do that.

This subject cost me a 6 pack a few years ago. I put a new hose and bulb on my boat and it would not pump up firm no matter what I tried. I called my boat shop and he told me to get in boat hold the hose straight up with the bulb head high and vertical. I told him if that worked I'd buy him a 6 pack. It pumped right up and the bulb pressurized as it should. Here's why. There is a one way check valve in the bulb and if the hose has air in it the valve won't always seat and hold pressure. Holding it vertical pumps all the air out and the back pressure seats the valve. Once it is primed it doesn't really matter how the bulb is laying. He said doesn't happen every time but when it does that's how to fix it. One 6 pack of Bud, please!

They say vertical for best results. Never thought it mattered, but I now always prime in the vertical position.

New means nothing . Replaced one a few years ago and motor never ran right . Took it to shop . Easy fix . They put zip ties on lines at the bulb ends and tightened . Problem solved .Bulb Bought at Walmart three days before taking to shop . Sounds very similar to your situation .

Arrow pointed up and never use Attwood bulbs.

If you did not replace the fuel line but only replaced the bulb it could be the old fuel line. I had the same problem a few years ago and in the end it was the fuel line that I did not change when I changed the bulb. That being said, the earlier posts stating that the bulb should be in the vertical position with the tank side pointing up is how they are designed to make the check valve work.

Just my 2cents worth...After you hand prime, the fuel pump should take over. I had a problem with my outboard and traced it to an old pick-up tube inside the portable fuel tank that had dried out and cracked
above the the gas level inside of the portable tank.
