84 Chieftain gas tank leaking

[johnfrederick]

My Chieftain just started leaking gas out of the top of the tank when I start it. The tank is full. Is this expansion happening when the engine is started or ??


Thanks, John

When you start it, the engine fuel pump is drawing the fuel through the fuel line connection..Located at the top of the tank..It is probable leaking at that connection..When you shut the engine off, the fuel drops back into the tank and then there is no more leak..

That is my guess..

That is where I first noticed/knew my fuel lines had rotted out. A virtual dribble from the front passenger corner of the fuel tank.As noted above only when running.

Thanks for the feed back. As this project was a complete tearout the floor has yet to be finished. As I have to get to the top of the gas tank is it a better option to cut a hole in the floor to access the top of the gas tank ?

Thanks, John

That is what I am doing on my project..But I have already removed the tank to fix it..Before I put it back in, I will create the trap door for it..

What you need to do is cut the floor out and be careful not to damage the tank with the saw that you use to cut the plywood..

The distance from the tank to the plywood is only 1.5-2 inches..So be careful not to cut the tank with the saw that cuts the plywood
