The engine started to lose power on a hill and by the time we got to the top the engine was making a trerrible sound. All the guages were reading normal. The gmc dealer or even head office are not willing to replace the motor. I feel that they should replace the motor for it is not our fault that this happen. We maimtained the truck to the highest standards.

Problem with fuel system evac canister. The canister, located in left front of engine compartment has a fresh air vent opening for partial venting of vacum directed towards fuel vapor control. It is covered by a loose fitting cap. This un-protected opening allows dirt to enter the top of the canister and eventually clog the opening. When this occurs the entire vacum force is apparently directed to the fuel tank causing fuel tank to collapse. An older model truck (I believe it was a 1997) was examined and a similar canister fresh air vent was stamped with the words "air cleaner" though it too was not connected to the air cleaner but was only covered by a loose fitting cap. This problem is probably not evident in vehicles operated on highway only. A local service station, john melhiser's amoco, petersburg indiana, related to me that he knew of 3 other area pickups (farm use) that experienced this problem. Symptoms of emminent fuel tank collapse based on my own experience are: 1-increased vacum in fuel tank as noticed when removing the fuel cap; 2 fuel gage begins to malfunction (caused by bottom of tank being pushed upward on the sending unit). I suspect that the effect is more pronounced at lower fuel levels. I contacted gm's customer service # jan 26 this year. I contacted them again march 16. They indicated that the problem had been noted but that no firther action was planned. Gm indicated that a "product allegation report" could be filed if the problem caused significant property damage or bodily harm. I suggested that they should at least produce a maintenance insert for the owners manual and service bulletins since dealers I checked with were not aware of the potential for plugging of the vent and collapse of the fuel tank. A more secure fix would be to vent the suction to the air cleaner (as was apparently intended on the earlier model) to ensure that foreign matter does not clog the vent.

This problem occured first in october 1998 and courtesy pontiac, where the vehicle was purchased did not find the problem! Last week upon returning from new mexico the engine lost power in missouri and I stopped at a gasstation and found that there was no coolant in the tank. This was refilled and one exit further the oil was checked after the problem did not appear to be corrected. This time no oil was in the engine. Before the travel a gmc dealer in shelbyville ky did the maintenance on it, filling 5 quarts of oil in!
