The lowest point in the system is actually behind the pilot seat and that's where I wanted my fuel drain. I had this custom aluminum block made by my machinist friend Steve. He actually designed it to fit perfectly between the tubes.

I replaced all the 4 AWG wire with aircraft grade 6 AWG wire with solder-on terminals. |

Again I didn't want the firewall cutting through the grommet and into the battery wire. So I installed this custom made bushing. It's nylon and is about 1 inch long and gives the battery cable a nice surface to travel through. |

I put these cool rubber boots over all the ends. |

In the stock RANS fuel
system, the fuel drain is under the pilot seat. However this is not the
lowest point in the system and is not where water will collect. The lowest point in the system is actually behind the pilot seat and that's where I wanted my fuel drain. I had this custom aluminum block made by my machinist friend Steve. He actually designed it to fit perfectly between the tubes. |

The fuel comes in from the tanks to the top of the block and goes to an internal 'T'. The fuel for the engine comes out the forward facing tube. On the bottom is another hole where the fuel can be drained out (see next photo). Notice how the block is designed to fit around the tubes. |

This fuel drain is screwed into the aluminum block. |

This picture just lets you see where on the aircraft this is located. |
