i have no idea how this pump actually works or what the internals look like... but just from the sounds of it, think of a speaker and how it 'pushes' air at a certain frequency to create sound. i believe this pump uses movement like that of a speaker to 'push' fuel, and some sort of check valve so that the fuel that is in the pump at the time of pushing does not go reverse, and when it retracts it does not let fuel back in from the out port.
i cannot see this pump 'priming' itself or even sucking fuel. the best spot to mount it would be right back at the tank, at the lowest point. Make sure you have nice thick insulated wires going back there to feed it too. solder the connections too, do NOT crimp the wires together! it will work soooo good!
plus, if it is the speaker like type, i only see extreme heat being the culprit for it breaking. as in any stereo equipment... but at the same time, extreme cold may wreck the pump if it is using the magnetic pumping system... because the magnets would heat up really quickly they may be prone to 'cracking' :?
not saying that these pumps are bad or anything... but they're made in China right? :lol:
