You could eliminate the extra filter by installing a filtering gascolator similar to this: https://www.aircraftspruce.com/catalog/ ... gIU9_D_BwE Here is the data sheet: https://www.aircraftspruce.com/catalog/ ... 51data.pdf |

Jeff, I think you just cost me about $300. Thanks for the tip on this. I think it fits the bill for what I need. Much cleaner routing this way! |

Post subject: | Fuel line question |
I have to make a turn in my fuel routing. If you had to choose, which one of these would you prefer to use? |

If it were me and it probably is , I would NOT use the bent alum. tubing . Too many bends for me and the possibility of cracks ? The AN fittings strung together is in my humble opinion a better choice . In order to minimize the number of fittings and "bends" I used the Aeroquip 6011/AE701 hose for fuel and oil . RB |

Thanks Rich, I think I agree about the "S" shaped fuel line. I'm working out the fuel routing from the gascolator to the electric fuel pump. I plumbed myself into a corner by locking in the location of both the gascolator and pump. Now I have to make the fuel line fit between the two. I ended up going with the two 90 degree bends and coupler. Not ideal, but I don't see how I can make it better. |

Either version can crack. Neither should have any bind when installed. The aluminum āsā will be a little more forgiving in getting things lined up. Commercially built aircraft do all kinds of crazy bends on hard lines so I doubt there is any difference in reliability for a very low pressure fuel line. How did you bend it that tight? Nothing I have or looked at buying can do that. Would there be a way to loop a hose to fit or a hose with 2 nineties? |

Yep, I'll think about it some more, but I'm going to move on to something else for now. Usually, once I let things sit for while and I come back to them, I am able to see a better choice that I couldn't see before. As far as the "S", I just used a tube bender I have. Its nothing special, I don't even know where it came from. I did massage both ends a little tighter. I trashed many pieces of tubing that bent/creased during the massaging. |

That sounds a little like how I made the bend from my tank to the shutoff valve. The bend ended up being too close to one end so the flare had to be hand formed with a punch. |

Is it a bad idea to fit my cowl and cheeks without the engine hung? |

Cowl needs to be 1/4 inch below spinner with new motor mounts. Engine will sag that much. |

Post subject: | 200 hp IO-360-A1A fit in cowling? |
Sorry for such an ignorant question, but will a 200hp IO-360-A1A fit in the cowl/cheeks of a standard T18 without any modifications? |
