Polyethylene fuel tank physics?
Ok this is for the people who have installed or really know the physics of the fuel tank.
Right now I'm installing the fuel lines to my already installed polyethylene tank. I'm installing a BG220HR system and have all the fuel lines and most of the fittings to make it work. My question is about the three ports on top of the tank (feed, return, and breather). I believe they are 1/4-inch holes (really small) two by the fill tube spout and one on the far side of the tank. Is the fuel sucked up to the top of the tank or is there a specific hole I'm supposed to use for the feed line? How does the fuel at the bottom of the tank get sucked up to the fuel lines? I tried getting a mirror inside the tank this morning, but was not successful. Does anyone have any idea on how the physics of the system work?
