Thanks guys. Progress has been slow lately. Other stuff gets in the way.
Ted- no, I've only tried the one size so far. Lately I've had some luck with cutting the braided line at an angle and feeding it through the fitting. Of course it doesn't always want to cooperate. I used white glue to hold the fitting to the styrene sheet so I had both hands free to feed the braided line and hold the sheet. But the idea worked really good. Lately I've been working with a different size line, so I haven't used that jig.
Bill and Chris - thanks for the encouragement. When I dropped the engine into the frame with the fuel pump and line for a mockup, I discovered that the oil filters are almost blocking a hole for a return line on the fuel pump. I'll have to figure something out there.
Thanks for looking.
