Your crimped-on hose is leaking and needs to be replaced. You should 
probably replace the hoses on all 4, as well as all the other fuel hoses in the 
engine compartment, assuming they are all equally old. This is a very 
common problem. It can cause engine fires, but, unfortunately, doesn't make 
the engine run poorly.

The test in the Bentley is concerned about an internal leak, such that gas 
leaks thru the injector and into the engine. I gather that your leak is external; 
this is completely different. Frankly, I've never seen an injector that had an 
internal leak that made any difference that I could tell.

I have new injectors for $40, but yours can probably be fixed by carefully 
cutting off the crimp sleeve without cutting into the hose nipple underneath. 
Then you can just use a piece of standard 5/16" hose and a hose clamp to 
replace it. Remember: You MUST be careful when cutting off the crimp 
sleeve, or you'll make it impossible to get the new hose to seal.

Don't try to just replace the one piece that is leaking now. If you do, you'll 
find new leaks in the next fitting down when you put it back together. This is 
inevitable from the disturbance you must cause just to remove the injector. In 
the end you can do everything in 2-4 hours, or end up replacing one piece at 
a time and take the whole day.
