    Make sure fuel filter is on correct . Did you have to replace all items, or just wanted too???? Pump whining tells me lots of work is being done. I think the fuel pump filter needs another look, and if you put something
    in line to keep from dripping, make sure you did not leave a clamp off tool on fuel line. Fuel pump a factory replacement part, or from a third rate store????? I have changed lots of these, and look at filter
    again, I know it looks like it goes on only one way, but look real hard once again. Mike

    Ij was using the process of elimination. first replaced relay,then filter and then fuel pump. All this and no improvement. I;have just ordered a fuel pressure damper which I thought may be the real problem. The car sat for about a year and I drained out all the bad gas . Prior to that the car ran fine. I ordered the fuel pump from High Flow Performance on e bay w/lifetime warranty. I purchased the fuel filter thru Advance Auto Parts. I will re look as you suggest. Thank You Very much for the in
