[DML] Re: Lack of fuel pressure

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

Pulling the line off and letting it shoot fuel out is only a flow
test. You may see a good flow and assume it would give a good pressure
but if you actually stopped the flow and measured it you might see a
low pressure which would mean the pump was worn out or the accumulator
was blown letting the pressure dump back into the tank. You cannot
check out an injected system like that. Maybe the Primary Pressure
Regulator on the FD is stuck open dumping all the fuel back to the
tank. It might be the best thing to do now is to send the FD and the
injectors out for cleaning and testing.
