Finally getting the cowl trimmed up and fit, oil door in, rivets glassed over, sanding and filling pin holes-- next step is priming. Been working at this for months now-- time to move on!

Can you tell me how you cut out the blue plastic so neatly? We use a blunted soldering iron and a straight edge, but we still occasionally scratch the surface, and the plastic does not always follow the line!

The blue you see in that photo is masking tape---I use the same method as you for plastic but lightly on the plastic just to make a mark.

I just take off ALL the blue plastic the first time I touch the part, specially the inside and then the outside after I have done the match drilling. Yes it will pick up a few scratches along the way but you will scuff it before it gets painted anayway.

- In your build, did you have to plumb return lines all the way back to the tanks? If not, where did you plumb the returns to?

Yes Mike. Mines a 540, the tests done at Titan were done on a 360 b/c that's what they had in production.

And yes, I have return lines run back to the tanks via a duplex valve. The fuel system runs just like an automotive system with the returns hitting the tank as far from the feeds as possible.

We've done testing on how far the fuel return into the tank needs to be away from the fuel pickup in the tank to keep the return bubbles from getting into the pickup.
(BTW the amount of vapor bubbles in the return fuel is about 50% of the return content - it's a bit surprising the first time you see it.)
It turns out the return fuel bulkhead only needs to be about three inches from the fuel pickup in the tank. This is enough spacing to allow the return bubbles to percolate out in the tank without allowing them to get back into the pickup.
Of course there is no harm in having more spacing than this.

Just recently committed to a recommended option of using stainless grab bar ends attached to the firewall for cable and wire harness pass throughl. Happy with the way it turned out.
