Thanks. I havent looked up exact location but its a strainer in front of the fuel rails. Typical symptoms were sneezing at idle, hard start, and wont reach high rpm.

the tracker valve is located on the fuel/air rail, it maintains a preset pressure bias of 10 psi between the fuel side and the air side, they are known for leaking and will cause a rich condition or no start scenario.If it wont run, or runs rough, check for fuel on the air side schrader valve, if you get fuel out of there, its most likely a failed tracker valve. They are not hard to install
