1976 Mercury 150 not picking up gas.

[TampaBoater]

I have a 1976 mercury black max 150, v6. I replaced the primer bulb and it's not picking up gas. There is gas in the fuel filter separator, but when I prime, nothings gets through. Any thoughts?

Also, the steering cable seems to be stuck inside the part it connects to at the transom. Is there a way to free up the cable from that section?

Just ta be on tha same page. Are you sayin' you can depress tha little ball (might be a pin on that age motor. don't remember for sure) at tha end that plugs inta tha motor and not get fuel when ya squeeze tha bulb?

Oh yeah. Just a tid bit. If its a 1976 its a 175............

I am not sure what you are talking about. I do not see a little ball or pin at the end of the line hooked up to the motor. I will take a pic and post.

Is it still a "quick disconnect" fitting. One kind is a push and turn (coincides with your year) will be tha pin and a bayonet type (later years)will be tha ball.......?

It is not a quick disconnect type.
Its is a bayonet type a believe. The line from the bulb connects to the metal bayonet and secures with a regular hose clamp. I took pics but my phone isnt connecting to computer.

I did. Nothing. It's a brand new bulb I bought today. I can suck the gas out with my mouth, but the bulb will not push it out.

Don't take this wrong but does it have a arrow pointing towards tha motor. You would be surprised with tha answer from some folks!!!

of course. I am trying to get a portable gas tank with a different bulb see if that works.

 

[Dukedog]

Try ta find an OEM bulb. Stand a better chance of it workin' outta tha box but still no guarantee.....

Hold the bulb with the arrow pointed strait up. Some of the cheaper ones won't work unless you do. And, try it with a different tank. You may have a stuck anti-siphon valve in your fuel tank.
