Default Minimizing Fuel Loss during tunnel work

I need to remove my boost pump from the tunnel and was wondering what others have done to minimize the amount of fuel that will be spilt when servicing the line in the tunnel. Will having a closed throttle provide enough of a vacuum (like a thumb on the top of a straw) to prevent the fuel from the engine side from sliding down hill and running out? Obviously turning off the fuel selector is required, but anything else that helps keep the mess down?

I use a disposable diaper to catch any spill when removing either the fuel or oil filters, boost pump, etc. Works great.

Sounds reasonable but now the wife is going to wonder why I am buying a pack of diapers. Ha!

As the aircraft gets older, do you have to change sizes? - 0-3 months, 3-6 months, 6-12 months............

Seriously, good idea.

Close fuel valve, disconnect fuel line at the servo or carb, place catch can or something to catch the fuel, run the boost pump until it empties out the line.
You can hear when the line is empty by the noise of the pump.
There is usually a minor amount that gets trapped in the filter housing but easily absorbed with a shop towel.

Thanks, in this case, the pump is bad, so no way to pump it out.

If your in a position you can run your engine, run it and then close your fuel. It will run until it gets starved. That should leave only a small amount of fuel left in the system. If you can't run it, remove the line from the servo and lower it as far as you can and gravity will get some of the fuel out of the line.
Otherwise, diaper up!
