Brief Description: Connected breather tube, all fuel lines
I started off today by installing the VA-133 oil pressure hose from VA-128 restrictor fitting on the engine to the VA-168 manifold. Then I tackled the FF-705 breather tube. There is a very high-tech rubber hose (supplied by NAPA) that attaches the breather tube to a fitting at the top rear area of the engine. I secured the high-tech rubber thingie using stainless clamps—the lower part of the breather tube is secured to one of the engine mount tubes using hardware per the drawings. Next was the fuel system. I attached the VA- 139 fuel line from the bulkhead fitting in the firewall to the engine driven fuel pump. There is an O ring on the fitting that I lubed with a drop of engine oil. I installed a similar fitting on the output side of the pump. The fitting on the output side is also a “T” which a VA-128 restrictor fitting screws into. This fitting is used to connect the fuel pressure hose to the VA-168 manifold. From the “T” fitting a line runs forward to the input side of the fuel servo. The output side of the servo connects a line that runs up to the spider manifold. I used a very minimal amount of EZ Turn on all of the fuel fitting—threads only. The last item installed was the fuel overflow fitting that goes into back of the fuel pump. This fitting connects to plastic line that exits near the bottom of the engine cowling.
