Caribbeandude Posted October 5, 2007 Share Posted October 5, 2007 Yesterday i was busy in the garden and out of nowhere I hear a strange rattling sound coming from the gas tank of my pathy. I noticed it before sometimes after a drive when i turn off the car, this rattling sounds comes on 4 a few seconds. I was thinking maybe the fuel pomp keeps running a few seconds. But now i had not driven her for 2 days and this sound comes up. Any body had this before ?? Das it mean the fuel pump is going and I have to replace it ? My car is standing under a carport but in the afternoon the back of the car (gas tank site) is catching some sun, out here its always around 35degrees (Celsius) sometimes hotter. Maybe its getting hot ?? I don't know just guessing. Link to comment Share on other sites More sharing options...
Simon Posted October 5, 2007 Share Posted October 5, 2007 Could just be residual pressure in the tank causing a few little noises. To test, next time you shut her down, undo the gas cap to release the pressure, then tighten it back up. If it still makes noises, it could be something wrong, though, the fuel pump itself shouldn't make noise, even if it were to go. Link to comment Share on other sites More sharing options...
Vsicks Pathy Posted October 5, 2007 Share Posted October 5, 2007 I have to agree with Simon. There isn't anything that can rattle really fuel pump wise. It could be a baffle that has come away though. Also your fuel pump pressurises the fuel rail, hence it may run after you switch off for a very short time and (with the ignition on) before it fires up.

It sounds electrical, I don't know, I will test it when I'm home tonight. Thanks Link to comment Share on other sites More sharing options...
