I have not owned a gasoline vehicle for 30 years so I'm a little rusty on gasser fuel system. I am looking for a connection where I can hook up a vacuum pump to create a vacuum in the tank so as not to spill any fuel when I r&r the leaky return hose. I have done that r&r a leaky return hose on my 85 300D without spilling a drop of fuel w/o draining the tank. I understand the risk involved and will take all necessary precautions so don't worry. |
That's a vapor line. There are others too and an expansion tank.

My feeling is that it will be easier to clamp the fuel exit hose from tank, disconnect it at bottom then run the fuel into a low level gas tank (I used an outboard motor tank). This after first siphoning most of fuel out of tank. It's not a big deal to do really.
If you do it with vacuum don't apply too much! Don't want to collapse the tanks. Couple of inches Hg at most. Should be enough for a not too full tank. If you plug or clamp one end of your new hose, you may be able to pull old one off and slip new one on without spilling much. Good luck if you try that
