EFII Fuel Pump Enclosure ..... - 10.0 hrs

This is actually a multiday update. Some of the work was from Sat Sun and then today Monday. First I test fit the pieces one last time and then I mounted the pump to the base. I took some contact cement and glued a layer of 1/8 inch foam to the bottom so as to sandwhich the brakelines and wiring between the upper and lower layer of foam between the pump base and the floor of the plane. This should protect everything from the vibration when this baby is running.

Next I mounted the base and checked the enclosure fit over the pump. Before I mounted the filter base to the top of the pump I decided to safety wire the filter down to the base. I figure when the engines running even though it fits tight as is this will handle the vibration better. About that time here comes the FAA for an airport inspection and they wanted to look at a REAL plane. I am quoting verbatum. These guys were pretty savy guys huh.

Anyway then on Sunday I went back out and finished the install and then wanted to run some fuel thru it to check for leaks and calibrate the tanks. I thought I was following the instructions properly but when I had added 10 gallons on the left side and then popped out the the engine monitor screen it only was showing about 1.2 gallons even though there was 10. I used the pump to pump the fuel back into the gas cans.

Next I worked on getting the flap enclosure installed so I can figure out the AOA flap switch. This is going to take some figuring out but once I get the wire run I will do that next.

Today I went back out and calibrated the right side tank. This time I hit the copy button after starting with 0 in the tanks. What it does is it actually changes the actual number that was prepopulated in that column. By hitting the copy button at each 2 gallon interval you are reading the resistance based on how far the float moved in the tank. This is good as since the wing had dihidral you don't want it to be a linear scale. When you see the numbers as they change at each setting its not an even change between each 2 gallons added.

I took it up to 14 gallons and then added a 100 to 16 and 50 to 18 and 35 to 21. 14 out of 21 gallons is 66% full. When I took it out of calibration mode and went back to the engine monitor screen guess what the tank gauge said.... SWEET.
