After checking and reviving 5 different 5000 gas tanks it seems that the rubber gastank grommet is more likely than not the wrong size where diameter exceeds the diameter of the fuel pump barrel. This does make one wonder what has been going on with all these different sized grommets in use though all the fuel pumps have the same diameter.. The real trick is to have an immaculate gas tank or you are likely to encounter severe stalling problems, though the car will usually restart right away but then stall again when trying to accelerate. The final result may well be the failure of your very expensive in tank, electric fuel pump. The good thing is that the injection system is very robust in recovering from a crudded up gas tank after the tank has been cleaned and the fuel filter replaced. Never replace a fuel pump without checking for crud on the bottom of the tank.
I found a unique method used to get around the dirty fuel tank problem in a parts car purchased today. The owner had installed a fuel pump outside the tank, but near the fuel tank access port in the trunk. However, this may not be a good idea for several reasons though the car is still running: A spark here from the electrical connections with the gas tank cover off could cause quite an explosion! The pump is also designed to cool itself while submerged in the fuel and when submerged in fuel a loose electrical connection has no opportunity to ignite an explosion.
