Yanmar 3GM30F fuel issues

Start of the season I changed all the fuel filters. Just wanted to get that out there. Sorry, this is long winded. Anyway, we are motoring out on Saturday, taking some friends out for a sail. We are just away from the marina and in the channel. All of a sudden the engine just dies. Wind was around 15 knots, blowing the wrong direction, so I threw out the anchor or we'd drift into the shallows. I took a look at the engine and it seemed to be not getting fuel. I was thinking it was air in the system. So I bled the system and the engine did restart. Motored out fine and we got the sails up. I couldn't find anything wrong regarding the fuel lines. Didn't see any leak. Then later in the day we're out in the middle of the river and motored again and after about thirty minutes the engine dies again. So we are adrift. I removed the bleed screw on the small filter housing (the one on the side of the engine) and see it is dry. I tried manually pumping at the fuel pump and nothing was coming out the bleed hole. I removed the fuel line on the pump inlet and fuel was there. I reconnected the line and toggled the manual lever. No fuel. Seemed to be a problem with the pump. So I removed the fuel pump. Then I disassembled the pump (just four screws). The internal diaphragm looked to be OK. I then blew through the inlet and outlet of the pump. I think some trash came out. Anyway, I reassembled the pump and manually toggled it and it seemed to be doing more sucking than before I took it apart. So I threw it back on the engine and then when I manually toggled it, it pumped fuel. I bled the system and the engine restarted. Motor ran fine for the remainder of the day. So, I was wondering, since the engine is new to me, anyone have experience with these pumps? I noticed that it seems to have some small plastic valves or something in the top of the pump. Like maybe it has some type of reed valve or something. Think what I did has 'fixed' this thing? Maybe it had some trash in it? If I don't need to buy a new pump I would rather not. Thanks for any input. Leslie "Puffin" Cal 33-2

I replaced the fuel pump on our Cal 33-2 last season. It had started to drip, leak around the diaphragm into the bilge. No big leak, just constant diesel odor in the boat, and slight haze in the engine bilge. The local Yanmar service yard and parts supplier recommendation was to just replace the entire pump. His reason was the cost of the pump kit, and potential failure of non-warranted replacement if I did the work myself. His concern was most of the pump failures will allow diesel fuel to be pumped into the crank case, potentially ruining the engine. It was a good enough story I fell for it, and now have a partially worn out pump as backup in case of failure. But that is what my parts bin looks like for all my vehicles J Ymmv JOhn From: Ca… [at] yahoogroups.com [mailto:Ca… [at] yahoogroups.com] Sent: Sunday, June 15, 2014 7:49 PM To: ca… [at] yahoogroups.com Subject: [Cal_Boats] Yanmar 3GM30F fuel issues Start of the season I changed all the fuel filters.

Thanks for the input. The pump diaphragm looked to be in good shape. I see if that fails fuel is going right into the crankcase for sure. I did see that there are some kind of plastic parts in the pump top and I suspect they were giving me the problem. So they aren't in a pump kit. I guess I cleared whatever trash was in there, but it's probably better I get a new pump. It's no fun having it cut out in a tight channel, in a strong wind that's blowing you ashore. Though you never know when machinery is going to quit. It kind of added a little excitement to the day.

Leslie; Thank you from another Cal-33 owner for sharing your experience. Although I have not had a similar episode, you have enlightened me as to another area which should be monitored. Yes, the filters are changed by me every year, but actually having "gunk" in the line never occurred to me, even with the new filters. Hope you have a great sailing season. Leeds, Cal 33 Cythera, Bristol, RI We are putting our 1988 '33 on the market, with regret. If there is anyone you know in New England who might be interested in a boat we all agree is a special one, please direct them to me. Moored in Barrington, RI harbor.

Leslie and Leeds, This is off the subject but here is my questions since both of you have a Cal 33-2. The Cal 33-2 I have is a 1986 and I find the settee on starboard side to just be uncomfortable.

Steve; Not on Cythera. It is not the most comfortable, as you said. We just have a few throw pillows to "soften" the blow. As a double berth, it is our preferred place to sleep, over the V-berth. We have the pull out board which extends out to the table.

Not Leslie or Leeds, but I re-upholstered the main cabin cushions several years ago, replacing all the foam and fabric. For the backs I tried to create a little better lumbar support, thinning the top 1/3 and adding a little more in the bottom 2/3, rather than the tapered section we had. I also found a softer foam and used a better grade upholstered fabric rather than sunbrella type fabric. The bottom cushion still is short for leg length, which is fine for dinning several aboard. With just the two of us, we usually sit on opposite settees, with the starboard table side out for ‘puter or Ipads. Wedging into one of the “corners” is more comfortable. Sometimes we leave the full cushions down and with added pillows, it is easy to sprawl out for light reading or napping. john From: Ca… [at] yahoogroups.com [mailto:Ca… [at] yahoogroups.com] Sent: Monday, June 16, 2014 8:56 AM To: Ca… [at] yahoogroups.com Subject: RE: [Cal_Boats] Yanmar 3GM30F fuel issues Leslie and Leeds, This is off the subject but here is my questions since both of you have a Cal 33-2.
