Try squeezing it with the arrow pointing straight up. Sometimes the check valves are a little touchy.

Is the vent open on the tank? If not, open it. If it is already open, there may be a filter on the tank pickup and it may be clogged.

Why do you have a brand new bulb?

Re: bulb not pulling gas out of fuel tank?

The reason I have a new bulb is it did not have a tank or fuel linewhen I purchased it. Tank has 2 gal gas in it and it is a 3 gal. tank. The vent is open and if I close it and it sits over night when I open it next day you can hear air coming out of it.Been pretty warm here.. I heard that there is a pickup tube in tank that I should also check. Also something about an anti-siphon valve? Not sure how to check stuff inside tank, there is only the cap opening and its not very big.???? I had this tank for a few years and it had old gas in it. So I turned it upside down and shook it into a container to remove gas. Could I have dislodged something??I thank you very much for your help, you guys are great. John

jwh, this will tell you if you have a problem or not, do this.

1st, make sure the bulb is pointing in the right direction, the arrow on the bulb should point away from the fuel tank. Fuel flows through the bulb only one way. Check this before try this next.
Remove the hose from the discharge end of the bulb, have someone else hold a container while you squeeze the bulb, before letting go, put your finger over the discharge hole so no air can get back inside. (while doing this point the end of the bulb in the container so you dont spill gas all over the place)
hold your finger in place, letting the bulb reopen, squeeze again remove finger, than cover the hole again, repeat this 3-4 times.
So, squeeze,uncover the hole, than cover the hole let go of the bulb.
if this doesn't get the gas to your bulb, your sucking air in the tank/line somewhere.
I dont think you have air leak b/c you said......

"The vent is open and if I close it and it sits over night when I open it next day you can hear air coming out of it"

if this is happening, you have no air leak. if there is an air leak, it couldn't build pressure.
