These are really pretty decent pieces of equipment. All manual, nothing electric, and fully rebuildable. To refresh one all you need to do is replace a length of silicone tubing if it leaks. My wife had a really fancy coffee maker several years ago she got as a gift. It developed a leak internally somewhere and I traced it down to a split in a piece of tubing. A replacement from the appliance parts store was some really ridiculous price. So after looking at it for a few minutes, I thought it looked just like the replacement tubing for a Six Shooter, and only cost about 3 bucks!. And it worked like a charm! If I was the type that used a fuel pump, this is what i would use.
Type at you later,
