Eric - the most inexpensive but effective way is to buy one of the squeeze bulb inline fuel pumps you see on outboard motors. Splice this inline with the fuel system just before the inlet to the Racor. You can leave it in the system without any impact.
The fuel lift pump is a pain to prime the system, as you can't really pump it fast enough to be effective and it is really low capacity. It doesn't pump a whole lot, as the engine normally consumes about 0.3 to 0.5 gallons per hour.
If you need a new lift pump, you can look in the top menu under "Market", "Equipment Suppliers" and see the link for Yanmar parts.
