Fuel pump problems

[Ralph50]

2000 Jimmy, 4WD, 92,000 miles.
The car broke down again because of the fuel pump.
The pump was a Carter installed 13 months ago and I only put 10,000 miles on the car. I dont know if I should be mad at GM or the aftermarket supplier. Maybe if GM make their designs better this would not happen. I am an auto engineer and problems like this should have been fixed in testing and development. The other option for GM would have been to install an access hole in the floor pan to change the fuel pump without dropping the fuel tank. I am soo mad. I have heard other people always say, never GM again. I have owned GM cars for years and now I am finally fed up. I have worked with GM engineers for years and all we ever hear is lower price, lower price. I bet that the fuel pump manufacture could have put an extra 25 cents in that unit and it would not fail as much. Purchasing managers have ruined the domestic car quality. I am going to sell that car before the 4th wheel bearing needs to be changed.

If you replace the fuel filter regularly, the OEM pumps usually last 100,000 miles, anything over that is a bonus. With aftermarket pumps, (airtex, carter, bosch, etc)anything over 6 months, (regardless of mileage) is a bonus. There are countless threads on the forum about aftermarket pumps, and they all say just about the same thing, don't waste your time or money on them.

Same thing goes with wheel bearings, cheapie bearings will not last. Front camber should be set to zero degrees + or - 1/4 degree. There are two sets of roller bearings in each hub assembly. Keeping the camber at zero degrees distributes the weight evenly between the two sets of bearings and increases longevity of the hub assembly.
