New Brake Master Cylinder is in.. still no brakes. UPDATE

So I recently replaced with a Centric brand u13 brake master cylinder. required me breaking the tabs holding the fluid level sensor, as it was facing the wrong direction (probably for right hand drive?) Properly bench bleeded and pumped brakes a bunch of times.. put cap back on and lost pressure once again. 

Didnt see any leaking fluid from up top or around car.. so next step is to put her on ramps and jack stands and fill up and go thru the lines with a flash light and try to find it that way. debating on using UV dye which would make the detection easier with a black light.. but man. more money. yeesh. already ordered two new rear hoses... One is Dorman brand the other is Beck Arnley.. different brands as they were the cheapest two on amazon. $16 for both compared to $24 ea at Autozone. 

Already have two front stainless braided Rotora front lines waiting to go in. Also got 2 feet of steel 3/16" line and a compression fitting union and tubing cutter juuusst in case. Hopefully it doesnt resort to that. May have to buy another quart of DoT3 .. might not have enough to flush and fill and bleed 4 corners.. once its all done I have a nice expensive Perrin branded lawnmower air filter dust sheild (LuLz) called a brake master cylinder kozy ready to go on too !

pic: carbon fiber intake heat sheild fits around the jdm apexi S13 intake.. I hope it fits when I install the MSD box.. that would be sweet. Hate to toss it to the parts bin. I removed the Minion wrencher and left the little Nissan logo.
