>>>I always thought that it made sense to put the filter between the tank
and pump, to protect the pump. However, I was seriously schooled by John
Christian that this is not the way to go. Fuel pumps are designed to push
fuel, NOT suck it. Yes, they suck fuel from the tank, but that is almost
incidental. A fuel pump can push against the resistance of a fuel filter on
the way to the carb, but it makes life difficult for them if they are trying
to suck fuel through a filter.
So, the counterintuitive answer is that the filter goes between the pump
and the carb/fuel injection. If you look at any new car, you will see they
are all plumbed that way too.
