After realsing that I'd put the fuel inflow and outflow in reverse, it had become apparent that getting the bends and fittings on was impossible... needed another inch of room to get the pipes flared. I'd ordered a box of various AN-6 fittings and managed to find a sensible way of connecting everything together. Had to reverse the position of the gascolator, but overall, the installation looks good. Guess I'll have to file another mod request with the LAA...
