I've riveted the middle ribs into my RV-6 fuel tanks and am now looking at installing the vent lines, fuel sender, pickup and such along with the end ribs. I decided to use a flop tube on the left tank and while eyeballing the parts and the drawings I came up with some questions.
My drawings are pretty old. This kit was originally built in 1992 and has been in storage since that time.
So here's my questions:
Looking at the flop tube it appear likely that it will hit the vent tube if the default location of the vent tube (according to my drawings) is used for the fitting that goes through the rib. Can anyone provide any thoughts on this or perhaps newer drawings?
Reading some of the other threads about related subjects I see that several people have discussed fuel return lines. I don't have any idea what kind of engine I'm going to end up with yet - I'll make that decision when I get closer to completion but it seems like a good idea to build for the option of FI should I chose to use it. Again, are there any drawings available that show the recommended method? Seems like it would be easiest to just go through the baffle.
My drawings show an optional trap door to prevent fuel from running from the first (inside) fuel compartment to the second but this trap door is only shown for the hole near the lower edge of the rib - not the one in the middle of the rib. This makes me think that perhaps that rib should not have been machined with two holes or that both should have a trap door if I choose to use one. Thoughts?
Finally I'm kicking around the idea of providing some sort of access to the first compartment in case I need access to the flop tube. It seems like a huge amount of work to pull the baffle. How many people have done this?
Thanks in advance for any feedback.
