My car developed a fuel-starve issue at an autocross about a month ago. It had never done it before, but even with a full tank, it would fuel starve coming out of hard turns. On the street, in a straight line, nothing.

I took it to a shop that's really familiar with F-Bodies (although maybe not a lot of thirdgens pass through), and they dropped the tank and found this inside the tank. Basically one hose was going from this widget to the fuel pump, and another hose was coming out the other end. It wasn't secure in the tank, and they suspect that it would flop around interrupting the flow of fuel. They have no idea what it is, so they replaced the hose/widget/hose combination with just a single hose. I just picked the car up yesterday so I haven't autocrossed it to see if it's fixed.

The car was originally carb'ed but has a later TPI L98 in it now. Although it has an extensive autocross history, I'm not sure how much bastardization has gone on with it over the years. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif)

The fuel pump kit I bought came with a section of straight hose to replace it. I never had an issue like that. However I think that thingy held pressure in the fuel line because my pressure always dropped when I killed the ignition. I will say I had a similar issue, apparent fuel starvation while on course. But only when the NNJR region switched to Giant Stadium. It only happened there! I used a different gas station for those events, so someone told me to try a different one... and it never happened again. Did you change gas stations recently? Maybe their tanks are dirty?
