Where to check for fuel leaks?

[newtodiesel]

Hi all,

I seem to be having a problem with fuel leaking

If the fuel gauge is working correctly I am using a huge amount of fuel, no where near the 25-30 miles per gallon.

So far I have replaced a fuel line to the #5 Injector the looped line.
There was an obvious leak there, looked like the original cloth covered fuel line
I tried first with nappa fuel line 3.2 was not able to get the line pushed down tight and used weed wacker fuel line instead
I dont see any more fuel leaking there...

The cigar hose looks dry, the other injector lines look dry, the small clear plastic fuel filter is dry. The big fuel filter is dry too
Where else do I need to check for fuel leaks?? I can still smell diesel.
I have looked under the car while it is running and dont see any obvious leaks.
GIRL TERMS/pictures/diagrams would be a great help...... I have searched and have not come across a complete fuel system diagram
thanks all
