check your fuel filter.
Scout "Bart Senior" wrote in message . .. Hurricane Charlie was a wet firecracker here in Connecticut today. This year everything has gone either north or south of us. Yesterday evening, predicted winds from Charlie were 39 mph winds and very heavy rain. One broadcast stated two to four inches--which sounded ridiculous to me. To prepare for it, I checked all ECHO's mooring lines, pumped the bilge, went over to the HOOT and put bigger blocks on the trailer wheels. When I got home, I checked the forecast one more time, no change, before calling my friends to cancel Sunday's sail. Last night we had light rain and no downpours! I woke up to find overcast sky's and a totally different forecast for light winds 5-9 knots, and no rain! I checked four different weather sources because I could not believe the forecasters could have been so far off. They were. Today, I called everyone and the sail was back on. Four cool people showed up, helped me install my new backstay adjuster and backstay. Last we I pulled my backstay and dropped if off with a rigger to install two insulators in it. I was eager to get it installed on the boat so I could sail this weekend. I picked a long length to make the insulated portion of the backstay plus the lead in wire around 66 feet. 68 feet is a 1/4 wave antenna on the HAM 80 meter band and 1/2 wave antenna on the 40 meter HAM band. I'm looking forward to trying it out with my ICOM radio and antenna tuner. This set up should give me great regional coverage for the east coast on 40 meters during the day and 80 meters at night. I had a good contact with base stations as far away as Southern California from Block Island, Rhode Island, with similar length antenna a few years ago. I was tempted to put a third insulator in the middle of the backstay to build a loading coil around it, to center load the antenna, which gives better radiation pattern. I may do that still. First I want to test out my new antenna, which will take a bit more work to mount the AT-4 tuner and make up a cable to connect it to my IC-706 radio. I could not find anyone who would rebuild my Navtec backstay adjustor, and guarantee the work, so I bought a new one. I'd rather have a new one than spend the same amount of money rebuilding an old one several times. It was much easier installing the backstay with four people helping versus only one taking it off. Winching my friend Mike up 60 feet last Tuesday, by myself, was backbreaking. Today, with no wind and lots of people it was fast and easy. Monica tailed the big winch, and her husband George and I took turns on the organ grinder, while Dawson kept the slack out of the safety line. It may be overkill, but after feeling vulnerable at the top of a mast many times with only one halyard, I've started using two halyards a few years ago. Mike went up the mast again, and his climbing efforts were improved over last time--a huge help! The whole job took 30 minutes. It turned out to be a pleasant sail. The overcast sky's kept us from getting burned. We had only two problems, a wrap on the forestay when jibing the drifter around the Middleground Lighthouse, which was a pain to clear, and the engine quit when I was getting ready to dock. Having extra crew made all the difference in each case. When the engine quit, I immediately anchored in the harbor, and called the ferry on the radio, to let them know what was going on. It was probably a nice change for them to have something different happen. Fortunately there was room for the ferry's to get around us, while George and Mike pumped up the inflatable. The inflatable and outboard worked well to shove the boat back to the dock. If I had more experienced crew I might have tried to sail it in, but I wanted to back it in--so power was the best, albeit less elegant, option. For some reason the engine would start, but die when given some throttle, or simply quit after a few minutes of operation. It started fine every time. I checked the cut off valve and it was good. After thinking about it tonight, I decided it must be the in-line electric fuel pump I added to help bleed the system. I think if I pulled it out, the problem will go away. We'll see. All it all it was a nice surprise to sail on a day that was supposed to be heavy downpours and high winds. And the bigger than usual crew was a huge help. I didn't have to haul up my anchor or clean that sinking mud off it, or even ask anyone to do it! Monica brought sandwiches and drinks for all. It was a very nice day and came together well at the last minute, even though it was planned and canceled. I'm not much of a planner and usually sail with small crews. I just like to jump in the boat and go when the weather is perfect. But, at the last minute finding crew can be a chore. Next time, I'll plan even farther in advance, and invite even more crew. Taking a chance on the weather and planning in advance have advantages. I still don't know what to do about those week days when the weather is perfect and I can't find crew. ~Bart Links for information on the radio, tuner and hardware used are listed below.

Did it run OK after you changed filters. Air leak?

It didn't run at all until I changed the filters and bleed the
system. I'll bet it's either the fuel pump or else the return line. Either of those fits the circumstances. "Scott Vernon" wrote Did it run OK after you changed filters. Air leak? "Bart Senior" wrote All filters are new. "Scout" wrote check your fuel filter. |

I'd pull the filters again, just to be sure there isn't some restriction
there. Call me superstitious, but so many years working with fuel systems has taught me that new means nothing. Scout "Bart Senior" wrote in message et...

Why would the return line cause it to lose fuel when you open the throttle?
If the purpose of the return line is to return unused fuel to the tank, theoretically there is less fuel passing through it as you open the throttle up. Scout "Bart Senior" wrote in message et...

With a Detroit, yes, but other types of injector systems do it differently. With our diesel (Ford Lehman) for example there is almost no return at idle, the return flow seems to be proportional to throttle setting (although it jumps when the load changes). A blocked return line could cause the engine to die but it would be more likely to surge or be unresponsive to throttle first (disclaimer- I am not an expert diesel mechanic and never played one on TV) Your advice about checking the filter again even though its new is right on. Say Bart do you have a vacuum gage on the filter outlet? Fresh Breezes- Doug King |

Good points Doug.
Also, in many of the fuel pumps I've worked with, a severely restricted return line will blow the pump seal.

I find that very strange Doug. I have a Ford Bowman and have a very strong return even at idle. Also have a very neat system to bleed the system of air. Its a tank mounted above the fuel system that has a capasity of the whole fuel system. If I get air in the system it get trapped in this tank above everything else. On top of the tank is a valve for purging out all the air. It's great for removing all the air induced while changing filters off shore in a rocking boat. My return is just as strong at idle as it is at full throttle. I have a simms fuel pump what do you have? Perhaps the Bowman conversation is just far better and stouter than your lehman conversion.
