 |
|
After reading about an earlier RV-10 tunnel fire I made an opening in the
belly skin so I could quickly check the tunnel and clean the filter without
spilling fuel in the tunnel. It's a lot easier to remove the bottom cover
than to remove the carpet and tunnel cover. In my case I have to remove the
seats to get access to some of the screws. I left a piece of the original
skin that has the saddle and clamp that holds the filter so that the filter
would be at the right height. After a filter cleaning and inspection that
piece with the filter clamp is repositioned using a small plate to locate
it. There are 20 screws that attach the cover which may be overkill but I
put a nutplate at every other rivet. Would have been easier to do when
building.

BTW, I would be concerned that any kind of vent would introduce exhaust
gasses.

Your solution is the best, Albert. If I was building again, I would definitely do this mod. Now I have to decide if I am up to tackling it as a retrofit on my airplane. 
Getting to my filter from above is a real pain!

Here's how I attempted to tackle the filter access issue from above. I think it makes it quite a bit easier when getting everything aligned.

Thanks...
The only thing that has changed since I shot the video.
1) I decided to keep the aluminum hardline from the boost pump to the firewall.
2) I added a two cross support (between the tunnel walls) to support that aluminum line with Adel clamps. The photo is attached to this e-mail.

That is very clean. I'd think that anything which reduces the number of
fittings required in the fuel system can only be a good thing.
Anyone wanna buy an installed only once and never turned on Airflow pump
and filter?

Phil, Wow! the Andair pump is a much cleaner install. If mine goes bad I’m switching. Simpler plumbing and belly access look like winners to me. Fortunately, in 4 filter inspections to date I have never found anything in the filter. Before the belly access I always spilled a bit and left the tunnel open to air out for a few hours. Now, through the bottom, there’s no problem and I inspect that area much more often.
I did leave a tee fitting near the valve in case I wanted to add a purge valve later. Hot starts in hot country aren’t always easy.

Yeah, it is very simple and very clean. Almost too simple.
I keep waiting on someone who knows more than I do to say I missed something, but that hasn't occurred yet. I do like the combo assembly and the engineering of the Andair pump vs AFP's (not that there is anything wrong with AFP). Besides the recirculation feature, the Andair does not use vanes and therefore won't wear like the AFP. Instead it uses a series of expanding cavities to create a siphon effect that moves fuel through it.
I like the setup a lot but I don't know what I don't know. Hopefully there is no obvious fuctionality missing from the system or any additional liability I created in the process. I am a believer that fewer fittings and less plumbing equates to a safer and more reliable system.

A product called " Pig Mat" is an absorbent material which can be placed under the valve before servicing. Less fumes to evacuate. Just through it outside, in the trash, away from a combustible structure.

The one thing I heard in the video was that pump was for the o-360. So the Question is how much fuel will it pump?

Pat,
Here is a thread that discusses it and includes Andair's response.
http://www.vansairforce.com/community/showthread.php?t=63129
It's actually more of a function of line size and pressure relief valve calibration according to those who engineer this stuff.
