Re: feul problem

John, If you are referring to me, I only replaced the fuel 
filter...nothing else. I don't now if the new one I had was defective 
or not but when I replaced it with a Purolator one, problem solved. 
Lee, if you are having fuel problems I would start from the very 
beginning of the system (before replacing anything). Check the fuel 
pick up line inside the tank, make sure it's still connected to the 
pump and also to the pump filter (it should also be inside the fuel 
baffle). If that all checks out ok, next start by disconnecting the 
fuel hose coming off of the fuel pump (the feed line, not the return) 
from the steel line attached to the chassis (leave the Banjo end 
connected to the pump). Jump start the pump from the RPM relay and 
note how the fuel is coming out of the hose...it should be spraying 
out like a garden hose so be very careful. If that's ok them re-
connect the line (make sure it's tight) and go to the next section 
(which will be at the accumulator) and do the same thing. Keep going 
down the line all the way up to the Fuel Distributor....the fuel 
should gush out like a garden hose all the way up to that point. Did 
you replace the high-pressure flexible lines when you replaced the 
pump? If so did you replace them with the same type of line and made 
sure that they were not kinked?

I would check that the steel line going from the Fuel Accum to the 
filter isn't twisted or kinked if you say that you disconnected the 
fuel filter from that line (not the flexible one going to the 
distributor). If you have proper fuel delivery going into the fuel 
accum but not coming out of it and the steel line is ok, the 
diaphragm inside the accum may have rotted out/broke and pushing the 
gas back to the tank through the return line located on the rear of 
the accum. Another problem could be that the pump is delivering the 
proper fuel amount when it isn't under load but is failing when it is 
under load (pressurized). You can take John up on his offer to test 
it out with a known good pump. Where did you buy the pump from? A 
delorean parts dealer or from a local auto store? I wasn't aware of 
this before but I was told not to long ago that there were different 
styles of pumps that were made that all looked identical. If you got 
it from a Delorean parts vendor I wouldn't worry about that....if you 
got it from a local autoparts store then what is the Bosch part 
number off of it? Someone on the list like John H might be able to 
check and see if it's a good number.
