(I've got a 503 DCDI.) This was a topic at our last club meeting, and Roger Hankins and I are also discussing it - so I thought I'd throw it out to this list.

It is about 30 years old and has about 3000 hours on it. It is still pumping, every time I crank the little Kubota. Of course, the Kubota lives in a different world than the Mikuni on your Rotax. It also pumps diesel and not gasoline. If the Kubota quits, no sweat. I can not remember how often I changed out or overhauled Mikuni fuel pumps back in the day when I was flying two strokes. Every couple years or so. They are extremely reliable. Three parts: Top half, diaphram, and bottom half. About the only thing to wear out is the diaphram which also acts as the gasket. How much does the overhaul kit cost? Make sure it is genuine Mikuni. LEAF was selling a kit many years ago that was not Mikuni. I had a forced landing the first flight after I overhauled my fuel pump at the Flight Farm, Monterey, NY, 1989. Put the old diaphram back in, flew to OSH, and home to Alabama. BTW: LEAF grudeonly refunded my money for my fuel pump kit. Don't think I answered your question. john h mkIII ________________________________ Message 4 _____________________________________ Time: 10:43:03 AM PST US From: Dana Hague Subject: Re: Kolb-List: Rebuilding Fuel Pump At 01:29 PM 3/15/2007, John Hauck wrote: > >Make sure it is genuine Mikuni.

The pumps are so cheap doesn't it just make more sense to replace the entire pump than to rebuild it? OTOH... the previous owner of my US made a forced landing (fortunately on the airport, but he still broke a gear leg) when the brand new fuel pump he'd just installed failed. Apparently it had been sitting on the shelf for some time, and the diaphragm had dried out. He actually did pretty good considering it was about his third solo flight in any kind of airplane (he's got a lot of PPC and gyro time, and prefers the gyro, which is why he sold the US to me). -Dana -- -- I started out with nothing. I still have most of it left. ________________________________ Message 5 _____________________________________ Time: 11:37:58 AM PST US From: "boyd" Subject: RE: Kolb-List: Fuel Filter / Water Seperator Hi gang, Considering installing a Racor Fuel Filter/Water Separator in place of regular fuel filter. Normal Mister Funnel and preflight fuel samplesshould take care of fuel source and condensation problems, but with ethanol fuels in our future would this be enough? Water and alcohol mix quite readily. Would a water filter tend to separate the alcohol along with the water from the rest of the fuel?Could a water/alcohol emulsified mixture get by normal fuel checks? Not worth worrying about? Would like to hear general comments and as well as from those who may be using this type of filter. John Ratcliffe >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> If we get a small percent of alcohol in our gas.... then we will have no concern for water in the gas..... unless we get more water than alcohol in our systems.... a water alcohol mix of 50 - 50 will mix and burn without problems in our fuel.... the water wont separate out until the water is greater than 50 % compared to the alcohol in the fuel. to check for alcohol in the gas is quite easy... fill a test tube 1/2 full with water, then draw a line,,, then fill it the rest of the way with gas, shake it up and let it settle. The difference between the line and the water / gas line is the amount of alcohol. Now to test for the purity of the alcohol will take a bit more time but is done in near the same way.... fill the test tube to the first line with gas.... slowly put in drops of water and shake between drops. When you first start noticing water in the bottom of the test tube, you will know how much water the alcohol in the gas will absorb before it starts to settle out. For example... if you have a test tube marked from 0 to 150 CC... fill it to 100 with gas... if it is 5 percent alcohol in the gas... you should be able to fill it to the 105 before the water starts to settle in the bottom.... if you only get it to 102.... then the alcohol in the gas already had water mixed into it,, or it was only 2 percent alcohol in the gas to start with. Any way until you get enough water into the gas to cause it to settle out,,, it will burn ok.

Prior to the flight, I raised the needle jet one notch on both carbs in hopes of eliminating the EGT spike in the mid-range RPM. I also put a strip of duct tape down the center of the oil cooler to see if I could get the oil temperature up. I saw 130 degrees on the first flight, and the manual indicates optimum range of 170-212 degrees F. The flight went very well. I like this engine! The EGT was more consistent across the entire operational RPM range (no big mid-range spike), running about 1290 degrees at 4,900 RPM. This is at 6,000 feet density altitude. The strip of duct tape across the radiator raised the oil temperature to around 140 degrees - still not high enough. The oil temperature pickup is at the bottom of the tank, so I'm sure the oil coming out of the engine before going through the cooler is higher. For you Rotax 912 drivers - where is the oil temperature probe located on your installations? Also, what are your EGT's at maximum power, and at 1,000 RPM less than maximuM? The HKS has the same carbs as the 912. After the flight, I refilled the two five gallon gas tanks (standard Firestar tanks). It took about 4.2 gallons to refill. That is with 2.5 hours running time, with 2.2 hours in the air. Most of the two flights were in the pattern, up and down with a total of 16 landings. I believe ten gallons of fuel will probably equate to 4 hours of flight time with the HKS. Best I could do with the Rotax 503 was 3 hours. That's averaging 50 mph cruise. More later, as I get more time on the engine. -------- Dave Bigelow Kamuela, Hawaii FS2, HKS 700E Read this topic online here: http://forums.matronics.com/viewtopic.php?p=100915#100915 ________________________________ Message 20 ____________________________________ Time: 07:52:40 PM PST US From: "John Hauck" Subject: Re: Kolb-List: Re: Firestar II HKS Conversion located on your installations?
