Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

You need to replace the wiring harness connector at the pump when the pump goes out or is disconnected. GM told me that the connector is made cheap and if it is not replaced it will short out your new pump after a few days. I went through 3 fuel pumps before I found this out.

Suburban 2500 HD

  • Automatic transmission
  • 68,000 miles

With only aproximately 68,000 miles i have had 3 fuel pumps replaced and now it seems like the fourth needs to be installed. each time the fuel filter has been replaced. Dealer has no solution except to replace fuel pump at a cost of about $500 to $600.
