Just asking for someone else...
Say a bike like an 1100 Virago. Runs carbs BUT has a very odd system with a small aux gast tank low down and a pump to push fuel back up to the carbs. Now assuming somone modified the whole bike a lot and the new tank no longer needed and aux tank and was well above the carbs would the pump be needed and more importantly would you need to modify the carbs? (shut off valve in float chamber?)
Cheers
