"Once you have eliminated the most likely, the least likely becomes most likely"

(Paraphrasing Sherlock Holmes)

So,

1. NOT flow divider: $500

2. NOT fuel check return valve: $300.
Found check valve hose end badly gnarled, replaced valve and hose end fitting.

3. Labor thus far: $300

SUB TOTAL around $1,100

An AI on field suggested following the drip UP from the bottom.

So

1. Cracked open a cylinder drain to confirm .....drip drip drip
2. Cracked open injector line...dry
3. Cracked open turbo vent line...dry
4. Scratched head: If not flow divider, and not check valve..maybe fuel coming UP?

5. Cracked turbo pressure ref line on fuel pump... Fuel oozing UP from pump.

EUREKA !!!

There should NEVER be fuel on the 'air' side of the pump, so some internal seal dying.
So the drool coming UP the turbo pressure ref line into the throttle,
then back down into cylinders.

Another $1,200 OH and maybe another $300-400 labor to remove and replace.
(I have the mesh screen on rear cowl opening, must de-cowl to remove and replace pump).

So about $3k to solve the drip.

Wife thrown from horse: Medivac to trauma center. X rays. She's fine.
...$6,000 deductible under Obamacare now.

Another unexpected $10,000 THIS month, plus the normal overhead.

What's to worry!?

At least my fuel will stop dripping. Happiness.
