With all the problems with these things it is hard not to believe we are trying to reinvent the wheel again. Motorcyle carbs like the mikuni and zenith are intended for gravity feed but some bike designs with their gas tank shapes do not feed well that way. So some have small electric fuel pumps with built in regulators. My kawasaki classic is one of them. You know what I will be trying. Used or rebuilts go for around $50. I will need a pair to have redundancy with my wing tanks, as I want no header tank. Though I suppose simplicity would be a half gallon header with overflows back to the wings with simple inexpensive auto pumps that run constantly.
