I want to see much I have. It sound like it wants to start but it doesn't. Just want start diagnostic it. After some research I believe I found a place to put it. Is it correct that I put it between the fuel filter and the the fuel line somehow?
Yes, I bought an aeromotive fuel gauge from a local speed shop some years back and ran it between the filter and fuel rail like your picture shows. If it's not included, you simply need a T to splice the gauge inline. They're very helpful for figuring things out.
