Can The Fuel Pump Be Removed From My Bike?
Can the Fuel Pump be removed from my Shadow?
The "fuel pump" on the dual carb vlx is not so much a real fuel pump, as it is an automatic shutoff valve to stop the flow of fuel should the bike go down in an accident. The valve opens when the bike is turned on and allows fuel to pass by to the carbs. It generates mild pressure to overcome the fact that it is situated well below the carbs on these bikes. The best way to run the fuel line from the tank to carbs is to take about 12-14 inches of line and run it in a clockwise circle from the petcock circling back around to the carbs, its very easy to install, and allows room for a fuel filter as well.
Consider this, if the fuel pump was so necessary, why did Honda get rid of it on single carb models? They did and didn't... They replaced the electronic shutoff valve with an Auto Fuel Petcock Valve which is vacuum activated. When the motor is turned on, the vacuum from the motor pulls open the diaphragm and allows fuel to pass through. In this setup, the fuel line doesn't ever drop below the carburetors. This design however was recalled on all single carb VT600 models from 2000-2007.
I have built numerous dual carb bikes and run them all straight to carb, its not so much a gravity feed setup as it operates off the weight of the fuel in the gas tank. so long as your vent tube or cap is vented you will be just fine! PARTY!
