Stus-List Fuel pump
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. 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

Ron, the model number of your pump is on the bracket that bolts the pump onto the bulkhead or wherever it’s mounted. Facet has a good site and really good product support. They also sell direct to Napa. If you go on their site with your current model number the specs are easy to find. Like another said it’s not really a lift pump but it’s listed that way. The pressure is maybe 6.5-8 lbs and it only lifts 24 inches max. There are many fuel pumps that will pump those specifications and you don’t need to replace the exact model unless you want to. Crazy Legs has a universal 30 hp and uses pump # 476459. The national motor components sales manager of Facet is Paul Puleo and his email is p.pu...@facet-purolator.com if you need to ask any hard questions. Paul 607-737-8371 office and 607-426-2736 cell. I had a non listed specs question (vacuum) and Paul was a great help. Len Mitchell Crazy Legs 1989 37+ Midland On.

I am trying to diagnose fuel issue. I dont understand pump wiring. There appears to be only one wire to pump. Where is it grounded?

Some fuel pumps ground through the case. Is the pump mounted on the engine?

Re: Stus-List Fuel pump
Just a thought: the Rich costing lift pump probably lasted at least 20 years. I suggest simply replacing it instead of introducing a new bunch of components to fail, (and stop if the power dies).

Re: Stus-List Fuel pump
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.

Stus-List Fuel pump problem?
Seems to be the week for Dave’s and diesel fuel problems. Here is my story to hopefully get the wisdom of the group. Last Wednesday I was out for a lovely sail (7.5-8 knot reach across Fisher’s Island sound for lunch and back). I had motored into the harbor on the other side of the sound for about 15 minutes and then back out again and no problems. I got back to the mooring area and the engine started and then quit. Tried a few times and it would only come close to starting if I gave it lots of throttle, but would still quit. Sailed to the mooring (which I hit on the first try under sail single handed in 15+ knots of wind- I impressed myself) put away sails etc. and then tried the engine again and it started and ran fine. I chalked it up to bad karma and went home. Saturday, we sailed to Mystic and motored for an hour into the harbor to the Seaport with no problems. Today we motored back out and after a long wait for the bridge to open (so about 30 min total motoring) the engine quit again and would not start. A few times before it quit for good, it would suddenly decrease revs for a second and then back up. Fortunately, the wind direction allowed us to sail out of the harbor and back to the mooring where it would not start. Then I started taking things apart to diagnose. (Universal M4-30, electric fuel pump) 1. Thought first my fuel gauge (reading half full tank) was mistaken or I had bad fuel. Pulled the probe into the fuel tank and with a flashlight was able to see that the tank was half full and the fuel looked perfectly clean. 2. Took the Racor lid off and found that the bowl was not full. It was about 1-2” down so at about the level of the top of the primary filter. Obviously not good. This triggered the thought that the sound the electric fuel pump had been making was not what I remembered. Instead of a rapid continuous clicking, it was more irregular and perhaps not as loud. So I am thinking either bad fuel pump or bad power connection from the key switch to the fuel pump. Does a dying fuel pump work one day and not the next? The other possibility seems to be a small hole/crack in the fuel line so the pump can’t draw enough vacuum to pull fuel from the tank. Not sure how to diagnose that and seems even less likely to allow the engine to work intermittently. Solutions/more diagnosis 1. Should I just buy a replacement fuel pump and see if it solves the problem? This is not inexpensive, but not a huge amount of money and a fairly easy test. Universal pump was about $230 from Toad’s Marine, but I seem to remember people on the list talking about automotive sources that might be cheaper? 2. Does one rebuild a fuel pump or buy a new one? 3. Is there a good way to distinguish power issues from mechanical issues other than a new pump? A friend suggested filling the Racor bowl with fuel, then turning on the pump and see if it draws the level down. The only problem with this is I don’t know how fast it normally pulls fuel so not sure how to tell if it was pumping, but not fast enough. Any thoughts welcome. Home now, but plan to go down on Wednesday and work on fixing the problem.
