full tank and sender replacement 67 440 wagon

[cherokeechief79]

while trying to find out the problem with my gas gage i recently filled it up to check the needle.
it all points to the sender and with all of your help ive located a sender for my wagon which seems to be the same as any b body.
how much gas do i need to get out before removing the sender.
ill have it up high in the rear on jackstands which will probably make it even worse.

Just a guess but I would say five gallons should be enough. Since you are putting it on stands, take the gas out while the car in on the ground. When you jack it up, set the front end a couple inches higher than the rear.

Before you take it out, hose down that area really well all around the tank and underside. Will help remove much of the grit thats going to end up in your face.
