    Out of an '02 F-body (WS6 Trans-Am).

    I read,

    this means I will only need (1) line from my tank.

    *** I will cap off the line to the charcoal can ***

    *** I will cap off the return line ***

    and all will be good (fuel wise) Right?

    Thanks again for leading me by the hand.

    You will need the return line to the fuel tank. In the conversion section there is a write-up on how to convert the OBS trucks to an LS1. Within the writing is a description on how to handle the fuel filter and supply lines. I don't do anything with the fuel tank vent hose except hook it directly to the brass fitting on the driver side of the throttle body when I go for vehicle inspections. Afterwards I disconnect it and cap the TB fitting and vent the fumes to the atmosphere.

    Thanks again "Red"

    Did more reading and searching. Found nothing that I hadn't already read.
    It did refresh my memory. My conclusion is there will only be (1) fuel line going to the engine.
    The return line will only run between the tank and the proper (vette) filter.

    Curiosity has me asking,,, why don't you just leave the vapor line hooked up?
    I live in an emission test community, wonder if this thing will pass.

    I think I am going to eliminate the charcoal canister. As I am going to run an air duct from each
    side or the radiator. I did find a 28" rad (local, all metal). Thanks again "Red" for the offer, some time back.
    The removal of the that "can" will also clean up the engine bay a bit.

    Yes, use the vette filter/regulator and the retune from it goes back to the tank and the feed to your one line on the fuel rail.
    I went to Napa for the quick disconnect lines on the vette filter.

    good luck and let me know if you have any questions on the harness.

    Yeah, I remove the line to clean the engine bay up. I removed the charcoal canister because it fugglies up the under hood area and I need the space for my air cleaner. They sniffer and visual test us once a year around here.

    Emissions here (PNW) every other year.

    The harness,,, I need to find a nice tight fitting grommet and fab a plate to cover the rectangular hole in the firewall where the old wires went thru. My PCM will be tucked in the same place as the stock one, since the stock one is no longer around. Yep, theives took it too.

    Can someone please tell me what the sensor is that is located on the right side of the oil pan (just below the starter)?
    Is it needed? ('02 F-body)

    The harness has no plug for this.
    The harness also has male plugs for the O2 sensors (so do my sensors), frustrating to say the least. Yes, I have read the pinned posts and found the part no's for the ones that I need (great, more stuff to buy). Now I'll have (4) O2's I can't use.

    That is the oil level warning sensor, not needed. That sensor won&#39;t be incorporated in the harness.
    I can send you some conversion harnesses to convert your existing o2&#39;s, or you can get 2002 v6 camaro o2&#39;s which will have the female plug on it. Either way will work.

    Thanks Allen.

    I will buy the v6 sensors.

    I am sure there will be more questions to follow.

    Edit--- Actually one right now. My MAF is a 3-plug. Which one (4-plug) do I need?

    the harness uses a truck maf, 5 pin, 99-05 truck maf will work.

    good luck and let me know if there&#39;s anything else,
