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)

My issue with them when used inside a fuel tank is that when tightened they tend to cut into the line. Fuel line continually submerged in gasoline will soften the hose and the clamps will loose tension. Worm clamps also have a nasty habit of backing off a little bit. Will they work yeah, just not ideal. I personally like crimp clamps also called 360 degree seal clamps. Page 7 of the fuel line PDF. I have also used the one Chris posted too. John
