Dual Primary Filters, the electric priming pump, new 4JH Yanmar, and 550 gallons of diesel in those two tanks to the left. Life is good! Thanks for watching
The electric pump can also be a backup pump for the engine mounted mech pump in case that fails ? It will deliver fuel through the mech pump through the pump non ret valves as the flow is towards the engine However a diaphragmpump fail will cause fuel to leak into the bilge or engine oil, I would fit isolating valves
Yes, the pump works as a back-up for your engines lift-pump. There are a number of complications though, as you said if it starts leaking, also some (certain Volvo's) have internal screen and if it clogs the pump won't help.
This is, like the reverso oil changing system, one of the things that makes boating more fun than work. Does it also have enough pressure to prime the injector pump? I didn't see you do that and all the videos I've watched for bleeding my system (Lehman 120's) show a messy bleeding of the injector pump by thumbing the lever a gazillion times. Regardless, this is a must-have system for PLEASURE boating.
Is your system pulling the fuel through the Racor filters or pushing it? The Racor manual indicates that putting a pump on the pressure side (pushing fuel) is not ideal as pumps emulsify water hindering filter performance. Curious how yours works - pushing (Pressure side) or pulling (Vacuum side)?
Works great, but it's only for priming the system, that's why the bypass valve. Normally when running the fuel is pulled through the filter. In the event of a low-pressure pump failure on my engine, I'm sure it'd work fine to get me along until I could make a repair.
Mr Beamer, I notice you run a 2 micron primary and a 10 micron secondary. I do this on my boat, because previous owner did it. If Yanmar is OK with a 10 micron rating, why be aggressive with 2 micron at primary? In my case the secondaries are very hard to get to and it buys me more time between addressing the secondary filters. I also run the Racor gauges and love them. This setup reports the suction between lift pump and Racor only correct? I have some twin Yanmar 4LH-DTE on my boat
Good question - I'm not on the boat this Weekend, but I think the secondary (most manufactures) is somewhere in the 2 - 5 microns. The primary would be a 10 micron, and it would last longer than my 2 micron. On my old Perkins, the secondary was a bugger to change, so I stretched the service interval by running a 2 micron primary. I just re-powered a year or so ago with the Yanmar and still have a case of 2-microns for the primary --> isn't it strange why we sometimes do things...
That black pump is like 35 years old, and came with a spare. Black Pearl is vintage. I can't remember the brand we used on King's Pride. Any pump that matches your voltage (12 volt for us) will work just fine because the demand is very low.
Thank you for the EDUCATION and the great visuals!

Aren't the fuel tanks to the right (forward) of the filters.... Yes
Thanks for this video! I've been trying to figure out a simpler way to do filter changes. This makes it very easily adaptable..
Happy to share - less mess, less time = more fun with your boat!
On the winter project list.
It's a great improvement to any vessel! You'll enjoy.
Great system. Thank you for sharing
Thanks for watching!
Been filling my filters with AFT for 30 years…works for me.. but this is a good idea

Yes it would bleed the injection pump if you inadvertently ran out. You would just cracks those two screws on the top outboard edges on a Lehman's!

Could you use an in-line pump like a facet purolater cube and not need the extra valve?
The reason for the valve is most pumps restrict the fuel flow too much. You don't want to starve the engine for fuel.
What's the brand of the priming pump you use?
