Turn off the engine, open the hatch and let it vent completely to the
point there is no smell. Turn on the ignition to the point the pump come
on. then y ou have 30 pounds of fuel pressure all the way back to the
injectors. Use you nose and sniff zones as close to the lines as you can
get - every where the is a connection. Use a good, narrow beam
flashlight - like a Mag light and focus that beam carefully on every
connection. You may have a weep that will almost instantly evaporate
with the engine running or when moving. But fully pressurized you may
be able to see a wet spot, even if it's not dripping. And make
absolutely sure the connections on the stupid plastic firewall
connection are secure and in good condition. There is a short piece of
hose on the front side of the firewall that connects the plastic fitting
to the fuel line. Those two connections and the hose are notorious for
leaking. I've had that hose leak first on the forward side, then the
rearward side, then the hose itself split. Just as a matter of
preventive maintenance that fitting and short hose should be eliminated,
lest it cause you grief at some extremely inopportune time. Be
pro-active on this one.
If you don't see something with this method, next step is - with the
fuel pump on - feel under each hose connection and clamp. If there is a
leak that can't be seen, you can feel the wetness of it.
Good hunting.
