I recently bought a 1994 BMW 1100 the fuel in the gas tank has been sitting. I took the gas tank off its full of rust. Can someone help me to label the parts here that are in the photo?

Sounds like your gas cap seal is leaking.

Try another fuel filter.If you have a carburetor,change the filter in it,if fuel injected,clean injectors.

Hello, You need someone to go beneath your car to check this out. You can have a rusted gas tank, a bad gasket on the fill tube or the vent tube could be bad.

There are metal clamps on many of the hoses in the fuel system. Your car is 16 years old and a clamp could have rusted off. There is the possibility of GAS theft if you have a locking or latched fuel door on the vehicle. Someone could have puntured the gas tank and left an open hole in it.

If that is found to be the cause, contact your car insurance company about theft damage to your fuel tank. Your comprehensive insurance should cover all or part of it.

I suspect that you have rust/particles in your gas tank that is being sucked up by your fuel pump and collecting in the fuel filter, blocking fuel flow. When the vehicle is at low RPMs, the rust particles settle to the bottom of the filter, allowing some fuel to pass. When you accelerate, the fuel flow jams the particles against the outlet, and blocks fuel flow. Change the fuel filter again.

I suspect that the alcohol laced fuel that is mandated now is the problem as alcohol is highly hydroscopic and releases water into the fuel sitting in the tank (metal)and causes rust. you may have to devise a method to **** all of the fuel out of your tank, and hope that all of the gunk comes with it.

I am having a similiar problem. bmw r 1100 s will only start with full choke and will die if I cut off choke or give it any throttle. This is my first bike and it has been sitting in a garage for 2 years. I took out the carbs, cleaned them and rebuilt them. I didn't find any residual in the carbs and they were very clean. Today, I was able to get the bike running and took it down the neighborhood but after the bike warms up it idles at 6K! Man... If I can't find any answers from this forum, I will probably drop it off at the motorcycle shop just down the hill from me. Any suggestions anyone? I think I will try to drain the fuel and give it new gas. But still....

the gas gauge is on the fuel pump assembly with in the fuel tank, you must have bumped it during reassembly. the only solution is removal. pull it out check for alignment and binding, reassemble being very careful. hope this helps.

Putting it on bricks will help from rust forming on under side of car. Get some fuel stablizer in the fuel tank, some people say keep gas tank full so it dosn't rust. Idk...about that though.. I'ld also take out battery. Oh, after storage, make sure you change your oil! And I'ld keep looking for more info. I've never stored a car so I'm sure there maybe more tricks out there I don't know about.
