Fuel Pump Assembly Done; Installed Silicone Gaskets, New Alternator, Tach Transducer
Today I took a personal day from work to take care of some things around the house and also to wait on a delivery that Fedex has been trying to deliver. For whatever reason, I sent the package from Van's via "Fedex Ground", but Fedex shipped it via "Fedex Home Delivery". I'm not going to rant too much about Fedex here, but suffice it to say that I'm pretty pissed off with them. I will make a note to Van's from now on to ensure that my stuff will never be sent on the "Fedex Home Delivery" truck again. If they can't ensure that, I'll just have the package sent to my office or via UPS. 'Nuff said.
Anyway...after a huge ordeal trying to get the package, I finally did get it. It had all sorts of goodies that I've been keeping a list of because I hate ordering a lot from Van's when they tack a goofy $4.00 handling charge on every order. In the above picture you can see that I installed the silicone rocker cover gaskets. I'm really glad I did this. The cork was already starting to stick permanently to the cylinders. The reason for the silicone is -- they're reusable and they will never stick. If you need to pull a rocker cover for whatever reason you just do it and don't worry about replacing the gasket.
I also received my new 60 amp "Plane Power" alternator. This thing rocks and is so much nicer than the Van's unit. The Plane Power model is internally regulated AND has built-in overvoltage protection AND a two year warranty (from date of purchase -- I guess I need to get this thing flying!).
Ok, more work on the fuel pump assembly. I pulled the fuel selector valve and put the 'T' on the bottom. The tee basically exists because there's a check-valve in the assembly. If the pump where to shatter internally or the filter where to become clogged the whole thing gets bypassed to send fuel to the engine. The only problem is -- I'm not sure how you would know it happened.
Ok, the pump is done except for the line running to the firewall. I'm still not sure where I want to install my fuel flow transducer. Some folks have installed their fuel flow transducers just ahead of the fuel pump assembly while others install it on the firewall (which doesn't seem like an easy place to put it, BTW). I put the carpet in the fuselage to try to ascertain where I could put the transducer. The transducer is thicker than the available space under the channel, which requires a) putting some sort of 'hump' in the channel or b) putting the transducer right up against the pump.
The installation instructions explain that the transducer should have 6 inches of straight tube before and after the unit. Putting it just forward of the fuel pump assembly gets it very close.
Here's another shot with the cover in place. BTW: THIS CARPET IS $$$$$ BUT AWESOME! It fits perfectly. It's from Classic Aero Designs, if you weren't aware.
Oh yeah, the easiest way to deal with all of this tubing stuff is to just remove the screws holding the fuel selector in place and pull the whole thing out. In my case the fit of the mounting plate for the assembly was very tight. I thought about chopping off one of the sides and riveting an angle in there, but in the end I decided to bend the place slightly so that it bows up in the middle. I think this is actually the preferred method over the angle because it took about 10 seconds and also it gives you MORE room under the assembly for wires and the bottom tubing runs.
I also received my tachometer transducer in the package. Unfortunately for Van's there is 0 documentation included with it (I assume it's included with the Van's tachometer itself, which obviously I'm not using).
Apparently it's simple to wire -- just run the red wire to 12-volt power, the black to ground, and the white to the left tach input (pin 32, white/green wire) on the Dynon EMS. Don't quote me on that though...we'll see if it works!
