low fuel pressure



Hello all,

I recently purchased a non -running D (vin 6295). It has 80,000mi was 
driven regularly until 1996. I've narrowed it down to a fuel problem.
replaced the fuel pump and filter, cleaned the tank, etc. checked 
the fuel pressure from the center line of the fuel dist. to the cpr--
less than 10 psi. same on the port coming from the fuel filter to 
the dist. I wanted to see if the new pump might be the problem so I 
hooked the pressure gauge to the incoming fuel line without 
connecting it to the dist.-- effectively creating no return path.
when i jumped the relay(using a remote starter switch so I could see 
what was going on immediately) I had fuel pump out of the now opened 
port on the fuel dist (backfeeding from the return line??). After 
searching the archives and checking the manual ( and not really 
finding this problem addressed) it would appear that the fuel 
accumulator has a blown diaphragm allowing the fuel to return to the 
tank without pressuizing the system. Is this a valid theory? Is there 
a simple way to check.
