<VV> Fuel issues! Smoking Gun?

[kenharri at comcast.net]

Hello, I have been having issues with my FC.  She runs well most of the time but has always (in the year I have had her on the road) stumbled under hard acceleration. Lately she just does not want to do more than a couple thousand RPM.  Yesterday it turned into a few hundred RPM, then nothing.  All the usual tricks would not work.  The best I could get her to do is run at 2000 RPM for 15 seconds then quit.  I hooked up a clean 2 gallon fuel source to the fuel pump input line, no change. I replaced the carbs with a known good pair, no change.  I replaced the fuel pump and also had no change.  Towed her home.  



I opened up the carbs and found them pretty clean with no noticable defects.  I opened up the 1 year old fuel pump and found both valves installed with the same orientation (see attached photos) with the inlet valve cocked off to one side.  I am no fuel pump expert but shouldn't they have an  opposing orientation to each other to suck through the inlet side then push through the outlet side ? 



You fuel system experts out there, where are you? 



Thanks for your input!
