Here's a couple. Please note that they don't show the supply side, which includes a pinch valve to turn the flow on and off. They also don't show the wheel collar restrictor on the line to the muffler to adjust the flow. I also use a one way valve, (available from hobby sources) in the line to the muffler to keep muffler gases/pressure from getting to the pump. This is the large B & B pump in these pictues. If anything, my little pump works better, besides being half the size and weight. You might note that I modified the B & B style pump by cutting off the big mounting lugs, and closing off their huge outlets and installing little brass hose fittings. The "B & B" pumps are just impulse fuel pumps intended for very large two strokes such as are on ultralights, etc. Even with these mods my little pump weighs half as much. This system smokes like crazy!
