Getting ready to awaken the beast...

Getting ready to start the engine.  So today was all of the little things leading up to that.

Checked all the fuel fittings, then put fuel in one side to test fuel delivery to the header.  I forgot to tighten up the banjo fittings on the fuel selector, so it pissed fuel all inside the fuselage.  Took me a minute to get it tightened once I realized where it was leaking.

But the big problem...  The fuel selector was in the OFF position, and I could hear fuel going into the header.  I immediately thought it was a problem with the selector.  After some head scratching, we pinched the fuel vent line, and it stopped.

I have the pillar headers, which are vented to the mains.  I T'ed the vent off the pillars and ran down to the firewall header.  Fuel is going into the header via the vents.

In hindsight, this makes perfect sense.  But this is not a flyable configuration.

My first thought is to put a check valve on the vent line between the pillar header T and the firewall header.  But I don't think this is ideal either.

But it is a place to start, and I will learn something.

We did accomplish cleaning out any 'sworth' in the tanks, which was minimal.  Inboards only.  Will do the outboards another day.

Next is to come up with a plan to correct the vent situation.  In parallel pressurize the engine fuel system and check for leaks.  I can start it with the vents as is.
