Message	I just experienced what may be a coincidence, but I loosened my gas cap and drove around, and the car appeared to lose fuel pressure fast and started hesitating badly under hardly any throttle. I pulled over and felt the fuel line post-fuel-filter, and it felt pretty soft. I haven't yet soldered up my fuel pressure gauge, but I'm assuming that having the gas cap loose kept the tank from developing pressure necessary for pump operation. Does that sound correct/plausible to anyone else? Thanks

Fuel pressure is def. - yobobrox 16:38:30 07/21/11 have you checked your FP regulator? (n/m) - RobZ32 16:51:18 07/21/11 Yes, I've done a few tests. Nothing conclusive either way, - yobobrox 22:05:30 07/21/11 Use your fuel pressure gauge it will help you determine what - Bo (Houston) 23:53:00 07/21/11 Found the problem - a bunch of debris got into my gas tank - yobobrox 16:31:06 07/22/11
