Fuel Prices For The July Pilgrimage

I have since corrected the design deficiencies but I can't do anything about the weather (no matter what ALgore says). One thing I can do is be very careful as to when and where I burn mogas. I will not buy it from a source which is unknown to me. This lets out every strange airport. I will not use mogas on hot days nor at high altitudes. Why is mogas from an unknown source worse than avgas from an unknown source? Matt |

... Why is mogas from an unknown source worse than avgas from an unknown source? Although I cannot cite a reference, it has always been my belief that Avgas is subject to tighter inspection procedures from the refinery to the customer. Also, I think that Mogas is blended more specifically for seasonal use. If the FBO is not selling a large quantity (compared to the size of his tank) you may get Mogas that is several months old. This means it could be blended inappropriately for the season - or simply be just old gas with less volatiles and/or water from condensation. Rich S. |

wrote: We left home and flew to Pullman in eastern Washington for the first fillup. When we were passing 25 mi. north of Helena, MT, the engine quit - vapor locked. Contributing factors were the high temperature (85 F @ 9500'), the (I suspect) old mogas I bought in Pullman, and my fuel system design, having the electric pump forward of the firewall and no forward-facing air scoops on the tank vents. What model of the plane is this? |

oups.com... What model of the plane is this? CP-323a Emeraude, although the fuel system was of my own design and construction. I have added a blast tube to cool the electric fuel pump and an air scoop on the vents to pressurize the fuel tanks. http://temp.corvetteforum.net/c4/elwood89//harvey5.jpg Rich S. |

I have a Zenith CH-300 with an O-320. I had a similar problem in the
beginning. I did as you have done, plus insulated the fuel lines, installed a small heat reflective shield over the gascolater, and ran a blast tube down to the mechanical fuel pump. Since then (about 1990) I have run over 9000 gallons of mogas through the machine with out problem. Although I will always let the engine (and the fuel pump that is bolted to the case) cool between flights. If I know that I will be doing flights without allowing a cool down period, I will put 100LL in one tank, and take off on it.
