[T3] Why is it that when I got my 73 SBIneverhadtoturnthekeysevera...

 Jim it very well could be a very small leak I can't see . I recall when I 
used to connect the pressure gauge on the left side small port with the 
screw and sealing washer while there was still pressuse not much fuel came 
out either taking out the screw or when removing the hose to the gauge . I 
used to place a rag there and only saw a small area of fuel , never measured 
it I would guess no more than a sewing thimble worth. Plus it's 30 PSI and 
in an area much higher than the pump and that fuel could come out from just 
the ring or the presssure side of the pump line since they all connect right 
at the same point a tiny bit would leak out that nipple putting that screw 
back in . Point being it does not take much just to drop the pressure to 
nothing. I have the switch with the two wires soldered to it all I need to 
do is find a place and wire it in. If I recall the pump ground and hot come 
out under the relay and the pump hot goes to a plastic covered connector on 
the realy so I can splice in between the relay and where the pumps hot lead 
enters through the fire wall. It's a two wire plastic covered cable. I have 
a few of those brass 1/4" adaptors one female and two male I can use yet 
don't want to destroy the plastic two lead plug on the relay.
