Lest anyone think that we don?t make our share of mistakes and errors, I present to you this simple fuel line that goes from the boost pump to the firewall of our RV-3 project. Remember that there are no drawings or even instructions for things like this on a -3 ? it is simply part of fabricating the fuel system with parts that you decide to use. Here is the simple finished line:
And here is the pile of tubing that gave its life in the development of the finished part!
This line that looks so simple exists in three dimensions in a very tiny space ? getting the bends in the right place is tricky, and leaving enough straight tubing to flare the end is even trickier. In fact, to make the winning piece, I had to put the flair on one end FIRST, then do a 90 degree bend. By actual count, this final piece was my sixth try at the part. Fortunately, a roll of tubing from ACS is pretty darn cheap (I am still using the roll I bought for the -8 six or seven years ago), so don?t be afraid to reject the parts that aren?t right ? get some more raw stock, and keep working at it until its right!
