I installed an electric, it is kind of like a spare, it is in line and the fuel 
passively passes through it using the engines mechanical lift pump.  When I 
need it, which so far has been to fill the filters, I use it.  I have it on a 
switch with ‘run’ or ‘jog’, but I haven’t hooked the + up yet, as I am not sure 
where I want it attached to, I don’t want it hot all the time, so I think it 
needs to be somewhere on the engine (Nanni, Kubota) so it is switched off when 
the engine is off.  I don’t recall the name of the lift pump, it is at least 20 
years old, was in there with my old Perkins 4-107.

Thanks for the suggestions Rich and Martin.  I thought the question would bring 
more responses from those who installed an electric pump.  On my cruise I met a 
guy who couldn’t say enough about switching to an electric pump.  Any way I’ve 
decide to replace the pump in kind and perhaps I’ll buy an electric one as a 
spare.

 

Thanks again;

Mike,

 

I did not see any reply specific to Yanmar fuel pumps but here is what I used 
on Calypso to lift the fuel from the tank:

Walbro Variable Frequency Reciprocating Fuel Pump, p/n FRB-22-2.  It was +- 
$110.00 at Fisheries Supply, Seattle and online.

 

I ran that pump for about 150 hours last year and it worked great.  For 
Calypso’s Perkins 4-108 the lift pump draws the fuel from the tank and pushes 
towards the engine mounted mechanical pump.  If the mech pump fails the 
electric will fill in however if the mech’s bellows fails the electrical pump 
could pump fuel into the crankcase.  Prepping for our trip around Vancouver 
Island I replaced both pumps and carried spare fuel system parts.

 

Back in the 980’s I owned a 1980 C&C 36 that had an apparent electrical lift 
pump failure (engine died at idle) that turned out to be a blown fuse hidden on 
the back of the engine.  Took me 90 minutes to find that one.  Fuse blew 
sometime during a 6 hour motor, at night (lights and radar running).  The mech 
fuel pump was able to keep up at cruise RPM but not at idle.

Hi.  I need help selecting an inline lift (fuel) pump.  While on our annual 
vacation our engine (3HM30F) started acting funny.  After running for 20+ 
minutes in the 2000-2200 rpm range the throttle would become unresponsive when 
put back to idle.  I would have to work the throttle to get the engine to idle 
and it would have to be 1000 rpm or more to keep from stalling.  Also; I’d have 
to put the tranny in neutral.  After a couple of minutes the throttle would 
return to normal.  If running in the 1500-1800 range there are no throttle 
issues.  I have notices that the engine cranks a little longer than usual 
before staring.  Perhaps 4-6 revolutions instead on the normal 2.  Anyway while 
on vacation the mechanic that replaced two copper washers on a couple of banjo 
fittings for $200.00 said my lift pump was gone.  Fortunately his $190.00 pump 
didn’t arrive on time.  Torrenson had one for less than $90.00.  

 

After spending another week in the Kingston/Thousand Island area we returned 
home without any issues but then again I kept the rpm below 2K and it was all 
down hill so to speak.

 

Not sure is the lift pump is truly shot but for peace of mind I’m going to 
install an electric fuel pump and I’m looking for recommendations.  Any 
particular make/model, gph, etc.
