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.

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.

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.

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. Mike S/V Persuasion C&C 37 K/CB _____ _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com
