Thanks for sharing Walt, you find a lot of stuff, too bad you aren't closer, I could use your eye. Meanwhile, I was planning on pressure (air) testing my fuel system in stages. 1. fuel pump assay, 2. 1+ selector valve and all cabin connections. Then that leaves each tank, and FWF. The plan was to use 50 psi and let it linger and if pressure drops then search for the leak. Fantastik works well for this purpose, taking care for drips on the aluminum of course. I have plugs for the connections and will not use an addition volume of air.

What do you think about this progressive validation approach?

Thanks in advance.

But wait! It has torque stripe on the fittings... how could it leak?

I personally like testing with fuel, others may have good luck with air but I've seen plenty of tanks that were "pressure" tested with air leak when fuel was put in them.

Plumbing is really pretty simple stuff, goop the pipe threads and tighten the **** out of them, then make a good flare and put it together, look ma no leaks

I used this...

and this...

http://www.amazon.com/UEi-Test-Instr.../dp/B000HHTY7Q

Or pay your HVAC guy a svc call to check for you. They should have both of these items. Use nothing corrosive around your plane or it may come back to bite down the road.

I've found that the aviation isle of my favorite bike shop has a good, light lube for flaring:

Kerosene is often recommended; I don't have that around the house, but this I do. The flares come out very smooth ad pretty ... unlike the ones posted in here.

OMG those flares look terrible, it's hard to catch in a Prebuy.
I was afraid it was going to turn ugly when you got into the tunnel.
Thanks for taking to time to make it right.
