2005 GV250 fuel leak from fuel level sender. Have not disconnected yet but assuming the sender itself cant leak wouldnt it be the gasket?

No, it's likely the gas lines, or yes the pipes coming out of sending unit to the lines going to or coming back from engine but yes part of the sending unit itself or the gas lines right there until it turns to rubber. These lines could be bronze welded but not while fumes of fuel exist so you put fumes from car exhaust through it after removing fuel pump and shaking that to get the rust out and check the filter at the botttom of pick up tube under fuel pump just watch out for the gas level indicator float as you remove fuel pump from tank, see my other post here tonight for more info.

Fuel pump replacement on a 2003 kia sorrento

Remove negative battery terminal, release tank pressure by opening gas cap, remove the rear seat, you will see a cover, remove the cover, you will now see the top of the gas tank and also the pump, the pump is located inside the tank and can be removed from the top, next remove the connector from pump, remove the lines, note : cover lines with a rag as you remove there may be a little pressure, this will help gas from spray all over, with connector removed and lines removed you will now remove the six bolts holding the pump in, lift and remove the pump, take note of the position, make a ref mark so you can reinstall pump in top of tank facing the right way. this is called a fuel pump module, here is a picture of the pump unit.10_6_2012_2_55_35_pm.jpg

Not gitting fuel from the gas tank to the fuel pump on a 1984 s10 blaer 2 door

this is a mechanical fuel pump that works off cam lobe, check fuel line from pump all the way to tank, notice wet or rusted line, split rubber lines that connect metal lines to pump and top of tank. disconnect fuel line at pump (suction) side. put a rubber hose on the suction side and clamp, install other end in a clear container with gasoline in it. attemp to start vehicle if it pumps fuel and starts then your problem is the line from the tank to the pump, if it doesn't pump it is the diaphram in the pump. If you suspect the pump and remove it inspect what drives it as well at this time. I believe it is pump or the supply line

Theres a gas tank leak comining from the top of the gas tank. what could this be /

Not knowing your milage or what part of the country you live in if they use salt on the roads. The leak is coming form the three fuel lines going into the gas tank and fuel pump. The fuel pump is inside of the gas tank secured by a large slip ring seal. From the years gone by these lines rust and since they are under pressure they will leak through. You will have to drop your gas tank to get to this. This is a ugly all day expensive job. Replace the fuel pump which comes with the new seal and fuel lines assembly. I could sit here and tell you the step by step procedure but that will take hours. The very best thing you can do is buy a Haynes repair manual for your car and year at any auto parts store @ Advanced, Autozone. Read the step by step in the manual. I have used these for 40 years with all my vehicles and saved tons of cash in labor costs. Be prepared to replace the gas tank straps and additional fuel lines depending on how bad the rust is.
Good luck and thanks for your question and I hope my suggestions help. Don't forget to rate me.

That is called the fuel pump mounting and it is normal for a truck of that vintage to have stuff drop on it like mulch and not get cleaned and rust out the mounting and the lines.

Need to replace fuel pump on 91 lumina

Pump is in fuel tank. It is a miserable job, do not attempt unless you are experienced at frustration. The fuel lines will likely be seized as well as the tank straps. Also the sending unit will be rusted together and will have to be replaced, the tank likely will be rusted under straps and will be no good to reinstall.

It will almost certainly be inside the gas tank. Pick up a Haynes manual, you'll be glad you did as this is not a simple job. You'll have to drain the fuel tank at least most of the way, lower it, remove the pump sending unit from the top of the tank, replace it and put it all back together.

Fuel leaking from top of gas tank

sounds like you are going to have to drop the tank out to inspect and fix. with luck it will be leaking from the fuel pump seal or the return line.
Bad luck would be if the tank is rusted out and needs to be replaced.
Syphon as much gas out of the tank as you can before you drop it , gas is heavy.
