Draining old fuel

Hi folks it's been awhile since I was around. Hope all of you are doing Great. Curious I tried to stick a clear hose to siphon fuel that's about a year old. I slid it in close to 2 feet and tried to pump it out and nothing. The tube is dry like no gas??? Gauge says 1/2 tank I believe it's not working properly. Is there any item in the line that prevents any item being forced down the gas filler line??? Thanks for any help. Oh and it's a 1990 bonneville LE, I am the original owner.

I believe there is something that blocks a hose from going past the bottom of the filler neck.

You should be able to disconnect the fuel filter, put stunting under that connection and then jump the fuel pump to empty the tank

I thought about that,a couple of tears ago I tested if the pump was working ,as it turned
out the tank was empty??
Can you explain stunting? And even jumping the pump?.Sorry to ask this much,I guess if I turned it over with starter it might damage something since the fuel would pump.out the fuel.

If like a 92-99, there is a green electrical connector hanging out right near the battery. If you run a wire to it from the positive battery post, it'll run the fuel pump.

That's sounds good, can I remove the Schrader valve at the fuel rail and use a hose there? Can I leave the fuel relay in?. Big thanks for help guys.

It would be easier to disconnect the fuel line off the rail. On my 95 I found the fuel pump relay, removed it and jumped the connections for the pump there.

I am bummed to say I never did this but this week for sure. I just got to my Camaro SS so that fuel was older. Can anyone tell me where is the relay on this car? And do I jump #30 and # 87 pins?

Not sure on the location but if your relay looks like this, then yes on the pins.
