Lift Pump replacement

 

I have replaced the lift pump and associated filters. New fuel line too. Before I restart the engine, does the system need to be purged of air? According to the manual, it is a self-bleeding system. But I am not sure and I may be over thinking it. Any advice or conventional wisdom before I attempt a restart?
?
Thanks,

Just turn on the key and let the pump run for a couple of minutes until it’s it slows to a steady click-click-click. Assuming it’s a Westerbeast.

With a lift pump you don't really need to bleed. As per Pete's comment let the pump run for a minute then go ahead and start the engine. It may take a bit of cracking and run rough for a few seconds but will smooth out after a few seconds. Just did this today on my 38-B4 when I changed the filters.

On the subject of lift pumps, I was thinking of getting a spare for my 1984 W13.
I understand that our engines are Mitsubishi painted Westerbeke red. Does anyone know what model engine my W13 is? Also where I can cross reference part numbers?

If you have cylindrical pump with a bottom filter, it’s a Facet pump, available from many discount auto parts sites at a fraction of the Westerbeke price. It’s not a Mitsubishi part.
You will need to determine if you have 1/4 or 1/8” npt outlets.

As mentioned the original pump was made by Facet. ?There is a replacement guide from Facet to make sure you choose the right pump. ?As long as you have the Westerbeke part number and you should be good.

That’s a handy chart. I see on the Facet site that the pumps have been upgraded to electronic activation rather than the mechanical breaker points, so they should outlive all of us.
Also, the Facet p/n is stamped on the mounting foot.
