After reviewing the few rare photos of other RV-4 inverted oil installations that I could find on the web, I finally came up with this. It's on the LEFT side of the firewall instead of the right side that is usually seen in other installations. The right side was a little bit "busy", with the heat muff hoses and the inverted vent tank located there. Hoses, fittings, and firesleeve to connect up this valve to the engine cost almost as much as the valve itself!
It took quite a few evenings of holding the valve in various positions to get the right combinations of vertical placement, access to fasteners, and hose clearance. Once I figured out where it had to be mounted, I bent and riveted the 3-piece bracket in one evening. I still need to place a doubler inside the firewall, as that stainless steel is pretty thin and I'm worried about developing cracks around the fasteners.

May 14 2017 - An interesting sky today.. overcase but with stormy somewhat threatening clouds and yet sunshine.. seems it can't decide it f it wants to rain or break out into a nice day so it kinda did both..

Ivy in the backyard. It transforms throughout the year from barren sticks covering the cinder block wall, to lush green leaves most of the summer, and now into a burst of color just before returning to the Earth as compost.
I purposely inverted the direction of this photo because it struck me as more interesting this way.
Photovoltaic industry has a great development prospect, and inverter is one of the most important products.
In the production process of inverters, inverters need to be moved up and down and flipped, and individual products weigh tens of kilograms.
If carry only by the staff's hands,it is not only inefficient but also a potential safety hazard (both for products and employees).
Therefore, tongli designs a power manipulator to assist in the handling, lifting and flipping of the inverter.
With the help of the manipulator, the work intensity of the staff is reduced, so as to improve the work efficiency, and ensure that the inverter will not fall in any case.
Are you interested in that?

It can make it easier to make out certain features.
Also, it looks like a weird eyeball - bonus!

Product Introduction:
1.For recreational needs (like: camping), the outdoor homework or the emergency power, This HEYA inverter generator can be workable.
2.High performance: The built in Digital Inverter can offer stable and clean power that means sine wave. You can safely power and charge some sensitive.electronics, such as your computers, video game systems, phones and TVs.
4.Low noise: Fully-enclosed structure design decreases sharply the noise of the machine.
5.Light weight: The volume and weight of HEYA inverter generator reduces 40%-50% of the traditional one. With the small compact design, it is convenient and easy for user to take power anywhere and store it in any tight spot.
6.High efficiency: The starting system is recoil, well it is very easy to operation, at the same time, and the engine comes with a smart throttle that can control the engine output based on power demand. Therefore, we can save fuel and reduce consumption. It is so good for the environmental protection.
Basic functions:
Low oil alert
Overload protection
Short circuit protection
After along time deciding what route to go down on how to edit this image. I stumbled across lime and white in my colour palette and when I clicked on gradient map I stumbled across this but I changed the lime to red. I'm pleased that white branches look very arty, to me anyway!
Today, we got a nice spring rain. So, after it finished, I went to the bog garden to see what photographic opportunities there would be.
The pitcher plant buds are plump and just about ready to open. Hanging at the base of each one of the flower buds, is a rain drop which acts as an additional lens. To see what image it was focusing, I had to get up tight with my macro lens. Turns out, you can see the fence and the house across the street. Neat experiment!
I had to invert this image so you could see the correct scene...
SkyTronics Inverter 300w 12v which was meant to allow me to run an Xbox360 in the campervan. Unfortunately it generated too much noise, and caused picture disturbance on the Akura TV. So I put it back on eBay.
An inverted version of my solarised cacti. Definitely needs to be viewed large; the small version looks sort of vanilla.
Finally the inverter module is revealed.
But, at first sight, there is no visible damage?
Sorry for the unsharp image and the low resolution... I can send the original version on request.
Composite of the sun on a very smoky day and a upside down cloud scene. Used PSCC focus area tool to select the trees, mountain, sun, and birds. super fast way to extract the original sky out.
