Put gas in it, after setting for a while gas is gone and the fuel tank is not leaking it has pressure in tank but sign of gas on floor.

If the gas is disappearing and you're seeing evidence of gas on the floor, then yes, the tank is leaking.

Look first at the gasket on the fuel level float sensor on the side of the tank. If you aren't seeing obvious leaking there, then you might start checking the tank for corrosion.

Is the tank completely empty?

Yes tank is dry, but it holds pressure, that`s why I ruled out the tank from leaking. I see you are not to far from me. Greenville Pa.

A small leak will hold pressure as long as it's covered by liquid. It will just take time to leak out.

Here's what I've done to diagnose this in the past. I used a testing tool like this:

https://www.amazon.com/OBDMONSTER-Unive ... B07P9VNC3H

It's actually intended to find leaks in intake or exhausts, but it works great for fuel as well. You put it in the neck of the (empty!) fuel tank and inflate it with the rubber ball pump, which gives an airtight seal. Then you use a small pump (bicycle pump or a small 12v compressor works well - don't hook it up to a powerful air compressor) and gently pressurize the fuel tank to maybe 5-6 psi.

You can then spray soapy water on various fittings, gaskets and fuel tank seams. When you start seeing bubbles, you've found your leak.

Remove the spark plugs, turn kill switch to off, cover the spark plug holes with rags, hit the starter button. Does liquid shoot out the plug holes?

Well I did work on one 1500 that had a slit in the hose from the pump to the filter and would leak when pressurized from the pump.

That's why I asked if the tank was dry. If the tank is completely empty, then you can rule out everything downstream: pump, hoses, whatever - because even if you were pumping the fuel straight overboard, it wouldn't *completely* empty the tank, as the fuel pickup screen is not right against the bottom of the tank - there is a tiny bit of unusable fuel remaining.

If the tank is completely empty/dry, then it has to be leaking out of the TANK.

So is this a new bike to you? What's it's history? How much fuel have you been putting in and are saying you are loosing?
Removing the pump is a good idea as the tank could be rusted if it sat a long time with less than a full tank of ethanol laced gas(absorbs moisture from the air).

I see you are new to the forum, welcome aboard.
Go to the new posters sticky at the top of the goldwing chat section and introduce yourself and your bike.

I bought it right off the showroom floor. It has been in a heated garage its hole life except when we went camping with the club and a trip north of me (Pa.) when we went to Greenville, Maine and to ,I believe Vermont to go up to the top of the mountain can`t remember name of it, damn that mountain is high. It only has about 28,000 miles on it, I had to share riding time between it and my 4 classic cars and my job, self employed.Im 74 years old.And it is time to get rid of my babies. I gave this to my son and want to help him figure this problem out.

If you don't have a fuel transfer pump, these work OK to finish emptying the tank to do a good inspection once you have the fuel pump out(below 1/2 tank before you remove the pump)

If the leak is where you can get to it reasonably easy you might try a fiberglass patch.

No, that was not him. It`s been like 20 years ago, I bought things off him.You may be too young to know about him. He was mostly sold stuff off of salvage bikes, only gold wings.
