Mike Pack well described the actual car that started the thread, but let me 
add a few general observations, for the sake of the list.... The rubber boot 
that supports the fuel pump may look smooth and supple at the top where you 
can see it, yet it can still be extremely rotten and cracked where it sits in 
the fuel. That's more than likely the source of fuel laying in a pump boot 
neck, which of course is below the top level of the fuel, if you're fuller 
than about a half tankful. Even a tiny crack can do it, especially since the 
fuel tank is under pressure due to the fuel injection layout. When the 
rubber gets gnarly like that, it's just impossible for it to get a good seal 
around the neck of the fuel pump. How the heck the fuel pump can work with 
the electrical contacts submerged is beyond me, although mine worked that way 
too. You'd think it would at least be a short circuit situation. Check 
carefully while it's apart. You'll probably need to replace more than just 
the boot. An old, wimpy pick up hose can suction almost flat, starving and 
soon wrecking the fuel pump itself, which is the most expensive component. I 
replaced everything rubber back to the solid fuel lines, just to be sure, as 
well as draining and cleaning the tank. The fuel lines that connect to the 
top of the tank are special. Get them from a DeLorean vendor. He can cut 
them to the correct length and even install the banjo fittings. Why waste 
time struggling, when you could be driving, or at least working to pay for 
your DeLorean? Your time is valuable, too!
