RE: [T3] fuel pump woes


The only symptom is it taking a long time to start it up. Once it
starts, it seems not to be any problems, it idles a little rough when
cold, but warm it runs well.

As I have previously stated, all else is well, he checked the fuel
pressure regulator and it is good. When you switch the car on the pump
comes on and then off as it should, so the relay is fine. The filler
overflow hose is good, the tank is relatively clean, as is the screen.
The fuel filter is new.

The problem as it is described to me, is this...

The fuel pump turns on with the engine, in order to produce 31 psi it
has to have resistance in the circulation line. This is done with a kind
of check valve in the pump. My check valve is not functioning, therefore
no resistance, and no good pressure. The fuel is just racing around at
full bore. It is having a hard time getting up to 31 psi. That is what
he explained to me. Does this sound wrong in some way?

Perhaps it just needs to be cleaned?

I think you need to look into this yourself and find out what makes them
think 
the old pump is "going out." I don't think they have any idea what they
are 
talking about, and whatever symptoms they have taken to say something 
about the pump, are probably being misinterpreted. What are those 
symptoms.
