October 18, 2008 - Firewall Forward

Finally getting around to securing the alternator and safety-wiring it.  First I torqued down the alternator mount and safety-wired it.
 
Then I did the same to the alternator arm.  I used a tip from the VAF forums.  I drilled two 1/8" holes in the arm and pop-riveted a countersink washers.  This gave me an anchor to tie the safety-wire to as shown.
 
I finished off the left-hand firewall passthrough. 
 
I had thought I would secure the fuel flow sensor to the engine mount on the right side between the gasolator and fuel pump. 
 

I ordered these two hoses from Precision Hose Technology.  One would go from the gasolator to the fuel flow sensor.  The other would go from the sensor to the fuel pump. 

I laboriously hooked everything up but I wasn't happy with it.  The hose-sensor assembly was very rigid was is not really a good thing since the engine apparently moves around quite a bit on the mount.  You want some flexibility in the hose for that reason.  So I took everything apart and installed the original single hose between the gasolator and fuel pump.

 
Then I tried installing the fuel flow sensor on the left side, between the fuel pump and carburator.  I used the original long hose to run from the fuel pump to the sensor, and one of the new short hoses to run from the sensor to the carb.  This came out great!  The new set-up is very flexible.  I feel much better having it this way.
 
I hooked the carb heat cable to the carb heat door arm.  Works great.
 
I had ordered a stainless steel shield for where the GPS antennas pass through the firewall.  I put a bunch of high-temp RTV over the rubber gasket, then bolted the stainless steel shield halves over it. 
 
I secured the manifold pressure hose to the engine mount with adel clamps.  The new adel clamp install tool made it quick and easy. 
 
I installed these white rubber boots on the Current Limiter terminals. 
 
On the right side, I secured the EGT and CHT wires to the engine mount using adel clamps. 
 
And I did the same on the left side, although I used silicon tape and tie-wraps.
