[quote]Hi All,Wondering if anyone has any experience with the Electromatic VP03E Low Fuel Sensor?  I was working trying to find out why my low fuel warning light was not indicating with the header tank empty. I removed the  Electromatic VP03E sensor from the header tank and the end of the sensor is very soft and almost dripping out the end of the reducing nipple. I traced the lack of indication to a bad bulb in the panel light, the light is fixed but if I put the indicator in the empty header tank the indicator light stays on as it should until I throw a rag over the end outside the header tank, then it goes off, shouldn’t it stay on until there is fuel in the header tank? Is my sensor shot?  Any thoughts appreciated,Lloyd CudnohufskyMod 5 912ul IVO IFANorthern Mi.[b]

Glad you brought this topic up, I have that same sensor in my kitfox 4 kit and was just about to ask some questions about it.  I wonder if the sensor is being effected by alcohol in the fuel?  Take care,  Jim Chuk

Lloyd, I'm not sure if yours is the same one, but  one of our members several years ago had a similar problem with his  sensor.  The tip appears to be some sort of acrylic and when he had a  problem and pulled it out to inspect it he found that the tip had softened up as  if it had a torch taken to it.  It melted to the point that it came out in  a long string.  Yours looks like the same one, but I'm working from memory  and I'm not absolutely sure on that.  It seems that this was before alcohol  was being used regularly and as I recall, it was thought that other additives in  the fuel may have caused it.

This may or may not apply.  A few years ago I was using some non oxigenated (no alcohol) Premium mogas with Justus Brother's octane booster in it.  Was supposed to raise the octane about 5 points.  Anyway I was wondering if that would affect my fiberglass tanks.  I had a tall plastic bottle that I used for testing fuel for alcohol and so I dropped some fiberglass pieces into the bottle and filled it up with the gas.  Over night the bottle was softening up to the point where the fuel started to leak out near the bottom of the bottle.  Didn't seem to hurt the fiberglass, but the bottle I had used lots of other times to check for alcohol was ruined by this stuff.  Never used that gas again.  Take care,  Jim Chuk  Avid MK IV (flying)  Kitfox 4 (building)  northern Mn

First of all I haven’t heard of let alone seen an aftermarket octane booster that actually works as advertised.  And I’m always looking because my early Miata pings like (never mind what) on low octane fuel.  The second thing is ethanol has an RON of 116 I wonder if it is reasonable to assume that most octane boosters are either ethanol or some other alcohol.

Hi Guys,



Noel is correct. If you can't run gasoline with ethanol then don't use the octane boosters in your tanks. Many are ethanol or methanol. Methanol is not as bad. He's also right that they really don't do a very good job on boosting. The 5 point claims are usually very generous to say the least, you may actually see 1-2 point gain. The gain is small. Studies pretty much bare all this out. People that race that use booster are at a level  above what we are doing.

 The assortment of chemicals in boosters, including but not limited to ethanol, glycerol, toluene and methylpropanol, all of which are highly-combustible and result in increased octane. Toluene-laden fuels burn slower and make less power on high-revving engines. 

Add too much of an octane booster and it will start to reduce your horse power. Octane boosters are better to help prevent detonation and for the most part a waste of money for the everyday engine. If you need to have a higher octane for a Rotax then buy fresh 91 oct. and get rid of the old gas that has lost a little octane from sitting 6 months.
