Here is transition from Black Fuel line to 666. 2 subtle things:
* Made the mistake of purchasing Aluminium fittings to save a tad bit of weight. BAD IDEA!!!! Hand tightening aluminium fitting into outrageous expensive aluminium body Flowscan 201Bs had both parts gall together. Wrenching it out ruined half the threads. Ground down a bottoming tap and was able to get a little more threads. Fit was just bout acceptable, but Reduxed in place "Sealed the deal" and postponed using the Noose. Moral don't use aluminium fittings on Flowscan aluminium body transducers. Use brass or steel, could use Stainless too. Teflon paste used as specified on Certified Aircraft installiations. The second nipple was OK, but don't test your luck.
* Notice just North of the aluminium angle, we bonded in place a G-10 stand off, so when "BigFoot" descides to step on the top 666 hose, it doesn't snap off the aluminium fitting. (can see what we were thinking better in prior pic.
