Hi all, I have the 85 truck with fuel leak problem. I replaced the
fuel line from the pump to the carb. I can idle the truck for 15
minutes no problem.  When I take it out around a few blocks fuel
starts running out the accelerator pump housing.  The sight glass in
the front of the carb during idle is fine( 1/2 way up).  When I get
back after a short drive the entire float section must be full as the
glass has no fuel line? Seems as if there is fuel flowing with no
stopping and filling up the carb and the pressure builds up?  Looks
like the to and return line are tied together at the carb?  A past
responce was the needle and seat was blocked by some dirt.  Could this
cause this problem still with the full fuel and pressure?  Could the
return line be blocked enough to let it idle, but not drive under a
load?  The front of carb with the sight glass has 3 screws on the
cover.  Will this get me to the needle and float to check things?
Thanks for any help.  Jerry
