I used {used} one for my gassers and they work very well. The big pump line tends to harden over time if you don't use them often. A replacement line is cheap and easy to install but sometimes hard to find at your LHS and ordering just a line is too much money with shipping. I use the little glow hand crank pump for gas now, it's rated for glow only but there seems to be nothing in there that gas effects. Mine keeps on working. I use a very old electric pump for my glows, I have a lot of glow engines and only a few gassers so it works out well for me. The 6 shooters do work very well though but the glow type seem to last forever.
