    can u use a turbo on with it

    Asked by: ernied 74
    We would recommend using this kit - Part Number: 546-70003 as it has the proper MAP sensor for a turbo application.

    Will this work on my 2001 8.1L?

    Asked by: BubbaMatt87
    The 8.1 Vortec engine is not interchangeable with LS based engine parts.

    Ok, Let me ask this....if the 40005pump kit will work.....how is the fuel regulated? If the rail has a return, is it regulated internally in the rail or do I have to put a regulator in the return line to stop excessive bleed off and loss of pressure?

    Asked by: Slightly altered
    You will need a regulator for this system or you can purchase this Part Number: 546-40003 fuel kit from Fitech.

    Would the 40005 fuel pump kit work with this setup and does this system have a return on the rail or single inlet? 

    Asked by: Slightly Altered
    Yes, that pump will work with this kit. The kit has a return port in the fuel rail.

    This should work on your application. You will need a transmission control to make it work properly.
