Critique my fuel system layout
(old message removed)

Aren't you missing a bypass tube?

That fuel filter is not going to be easy to service. Build a door in the bottom of the fuse directly under the filter. You will thank me every year at annual time!
I have installed access doors on quite a few RVs and rockets, including a RV10. They are very similar in construction to all the other access panels on the aircraft. |
Looks just fine.
You only need to worry about the rigidity of lines FWF. As Tom mentioned, an access panel will make life easier. I put one in on the right side of the tunnel. I know folks that have installed them on both sides of the tunnel as well. I've already had the opportunity to take both the filter and pump out and it was not a problem. This is even more important if you install a center console, which makes taking the tunnel cover off more difficult. |

That said, the picture shows about 90 degrees (total) in that Z bend, and that's plenty as long as the pump and filter can float slightly in rubber mounts. If they are truly rigidly mounted, then I might be uncomfortable with the line from the selector valve. |
I see that the filter is supported, but don't see that the fuel pump is supported. That's a lot of unsupported mass. I would also agree that adding a large removable panel in the right side would be a good idea. I have one, and it is not a problem to remove my filter to inspect it.

Duh on the bypass. Actually I think if your tunnel cover comes off fairly easy you don't need an extra access. Screws are screws and its good to look in there periodically.

Plumbing the new version AFP pumps is a breeze. Looks like you do have enough offset between the valve and the filter. Like Tom and Bob said, the filter in the tunnel is a little bit of a pain. Several customers now are mounting filters in the wing roots to make life alittle easier. Some of our European customers have mounted gascolators in the roots.
I would hate to spill fuel in the tunnel or cabin of an RV10---especially after all the hard work, carpet, leather, consoles etc. Tom |
