There, but for the grace of God, go I
Thanks for sharing your experience ... though you might be kicking yourself, you're kicking us, as well, to pay attention to everything. I'm currently obsessing about sealing my tanks, so I'm way away from running an engine, but, I'm filing it away for later. I'm sucking down as much VAF wisdom as I can.
I'm very happy that you found your bug! And that you have added to the wisdom store.

Bill,
That was kind of the intent. I'm not necessarily into self flagellation.
I find that the more of stuff like this that I read makes me realize I'm not alone in making an occasional dumb mistake and feel I can take a bit of embarrassment to put an idea out there again. Thanks.
And Ron, thanks. It feels good to have that behind me so I can move onto some of the remaining items. I'm really itching to fly it now though!

Torque seal = absolutely worthless. Perfect example of why. All it does is try to convince you its not necessary to check a fitting, when you should be.

....... interested in learning how this caused engine prob
Thanks for your post Jesse,
Just interested in the logical explanation why this caused your engine problem. Was it pulling air into the fuel lines but not leaking fuel externally and thus causing fuel starvation?
Cheers, Greg

Exactly Greg,
The loose fitting was on the suction side of the electric boost pump so it never saw positive pressure, only suction.
The electric boost pump was able to suck enough fuel through it even with the air to produce 30 PSI, but the mechanical pump was not. In addition, the mechanical would have to pull harder to overcome the additional friction losses of the fuel through the electric boost pump and the red cube as well.
Even with the electric boost pump showing 30 PSI, it was pulling enough air through the system to make the engine stumble.

Only the greenest of newbies have not had an experience like you describe. The rest of us just smile, and go, "Yep, been there; done that."
Above all, glad you found the problem!!!

Confession is good for the soul...And for the rest of us mere mortals
Did the same thing Jesse when first hooking up the fuel lines to the engine. Thanks for sharing!
