Mike, nice clean installation, looks well thought out.

I noticed in your pictures that the fuel pump wires appeared different colors. In fact it appears that you have red, black and white.  I just ordered a Dukes as a replacement for my Weldon, for which I could not get new seals. The two wires are both black and have a notice that mention that they are not polarity sensitive.

I have hooked mine up and have started the engine twice.  The strange thing is that after the engine has run and shut down I have fuel pressure at 16 or so.  Then I turn on the Dukes and watch the pressure drop to 1?  I am wondering if I have it wired backward?  I did not think that would be possible.  I am thinking about reversing the wires and seeing the effect.

Anyone have any thoughts for me?
