    Where to mount boost and fuel pressure guage?

    First off, my heading is wrong.

    I just got a Procharger for my LS1 F-body. I have a fuel pressure and boost guage to install.

    My first question is, how do I connect the fuel pressure line to rhe fuel rail?

    Second question is, where do I connect the boost gauge line? I have seen it connected to the power brake booster line, but where is the best place?

    Pics would definitly help! Thanks

    There is a shrader? valve on the front of the fuel rail under the black cap on the driver side. You have to remove the shraider valve and hookup the fuel pressure sending unit to the fuel rail. Sorry no pics but there is a t-fitting on the passanger side fire wall next to the pcm. It's a small black tube about the same size as the boost gauge tube, if you can't find it it is connected at the back of the intake manifold on the pass side. Make sure you hook up to the end that connects to the intake there is a one way check valve on the other side of the t-fitting so it wont see vacuum.

    Areoquip sells the fitting you need for the fuel rails $10 buck i think.

    Yes that is the best place.Unless you pull the intake a make a fitting to use the MAP sensor port.Every turbo car i bulid here that is where i put them for ease of install. you can run the line through the firewall with the computer wires.
    Good luck
