CA smog test collapses fuel tank. 1995 Suzuki Sidekick 16-valve 4x4, 4-speed automatic. LPFET Test.
Two years ago, my 1995 Suzuki Sidekick 16-valve, 4x4, 4-speed automatic passed CA smog at a Gold Shield facility. Afterwards, it had reduced power and the fuel gauge did not work. Neither problem existed before the test. I found low fuel pressure and speculated that both the gauge and pressure problems were a harness problem. I finally pulled the tank and found it badly imploded. The smog test station took no responsibility. I replaced the pump and was able to blow the tank out. There were no leaks afterwards. Two years later (just a few days ago) it went in for the routine test. I saw the mechanic fool around with the pressure test for a long time and he looked under the tank several times. It passed the test but, now, the fuel gauge reads differently and I suspect the tank has been damaged again. I will have to pull the skid plate and, possibly, the tank to make sure. What part of the test could result in a negative pressure on the tank? Is this a common problem with certain vehicles with today's test requirements? What is my recourse?
