Was driving vehicle, stopped vehicle, noticed that gas was leaking from underneath the vehicle. took car to dealership to diagnose issue. quoted $970 to fix. fuel nipple broke on fuel pump assembly. entire assembly had to be replaced. gm recalled 316,058 vehicles for this issue. my vehicle was not part of the recall based on the vin number. gmc will not compensate even though other yukon xl's and chevy suburban's have had this problem. i have a friend who owns a 2001 chevy suburban and he had the same thing happen to his vehicle. he had to have the same part replaced on his vehicle. this problem is a safety issue. looked at the fuel pump assembly that was defective and the fact that one of the 3 plastic nipples broke, i feel that this should be a recall. this part is defective. now gmc has a lifetime guarantee on the replacement fuel pump assembly. this tells m that they are aware that the original ones were faulty parts. so in other words we've got good news and bad news...we will guarantee the part for lifetime but it will cost you $970 for a part that i should not have had to replace. this was not due to wear and tear. they have plastic nipples on the top of the fuel pump assembly line. gas eats plastic. *tr
