Fuel System

Last night, the fuel plumbing was completed. Originally, the Jenny had few filters of any kind - fuel or oil. I read a lot of stories about Jenny pilots landing in fields with sick or dead engines. Often it was contaminated fuel. Conscientious Jenny pilots strained their gas through a chamois. Especially when they used a rusty steel gas can.

They didn't know better back in 1920. But we do now.

So, a decision was made to install a fuel strainer. We wanted it close to the tank, inconspicuous, and looking like it was supposed to be there. So, we cut the copper fuel line between the fuel tank and the wobble pump.

The ends were flared and EZ Turn was applied to the threads.

The gascolator bracket was secured to the firewall with some screws.

Then the fuel shut off handle was reinstalled.

And the line from the wobble pump to the engine was run through the firewall. We used a uni-bit to cut the hole.

Here is the engine side of the firewall. Eventually, this copper line will be cut and flared and a barb fitting installed. From there, a flexible mil-spec line will run to the carburetor.

Here is how the copper lines are secured.

Then came the moment of truth. A gallon of gas was poured into the tank.

Everything worked well. We did notice a leak around the pressure set screw of the Buzz pump. It was a new pump, so that should not have been happening. We removed the screw and found the o-ring was cut. A new one was ordered.

More soon
