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)

They make others for fuel lines that look similar but have a real nut and bolt instead. http://www.alertmotorsport.com/Product/SL+...ose+Clamps/1620 The worst part is that it would leak back into the tank if they didn't use the right ones and it would have to get redone. But I'm betting they would still hold 'enough' pressure to drive the car... also betting that it wont be an issue if they used ones from a fuel pump kit.
