My volvo has that manual lift pump but IMO that is worthless for drawing up fuel and filling empty spin on primary racor filters. I have a vent on top of the last resort fuel filter (on engine)and can bleed out nearly all of air and that works fairly well. The engine seems to run OK if there is a little air in the system and takes care of it but if there is an empty fuel filter, or dry fuel line it will not run very long. I think this manual pump will do the trick and keep my bilge clean when I change filters. I plan to install it in a place that allows me to pull the fuel from the tank and then push it thru all the filters allow the air to escape from the final vent. What I like about this in line pump is that when you are finished pumping you rotate the base 90 deg and it is like a ball valve inside, there is zero resistance.
