Thanks,


	Luke,
	I'd check in the tank if the pinched return line didn't increase
pressure...
	Did the tank/pump assy have a "pulsator" on it?  Looks like a turtle
and 
	goes between the pump outlet and the fuel line in the tank... If so,
remove 
	it and replace it with a section of high pressure FI line and
clamps.  The 
	pulsators love to seperate between the metal and plastic and leak
pressure 
	right back into the tank.  If not, ensure you used a good piece of
FI fuel 
	line between the pump and the line, and also that you have a good
pickup 
	sock on it... Pickup socks will collapse sometimes and plug the
inlet.
	Man thank god I'm not the only one..... I posted a reply to this but
forgot that this also happened to me! :-)
