I have always used a home made version similar to the one Perceval posted but not as complicated. I used zip ties and a yard stick. I added a small ball valve at the bottom of the loop in case it is far enough out to suck fluid into the engine. Hook it up, start the engine, slowly open the ball valve. If it is way out you can close the ball valve,adjust a little and try and open it again. I also use 2 stroke oil in it so if any does get sucked in the engine it will just burn and not hurt anything. It is also a good idea to have a big fan or 2 blowing on the engine while working too keep it cool.


I learned all I need to know about life by killing smart people and eating their brains.
