    88-95 obs return less fuel system parts (i need help)

    What all is needed for 4.8/5.3 return style fuel system in a 88-95 obs Chevy I don't mind if its a little extra work, but I'm having to pinch pennies here, as I only have 80-90% of the funds as it is depending on the price I can find my motor at. any and all help is appreciated. Thank you guys.
    Edit: made some typos, want to run return style system and not the vett filter.

    The TBI motor already has a return line, so would these two fittings all I need besides a pump

    I'm sorry, I meant use the return line. Not return less. I don't want to go with the vett filter.
    It seems a cheaper rout to only buy two fittings and use the stock filter and lines.

    If you don't use the corvette filter you will need a regulator to get the proper psi.

    I was under the impression that the corvett filter held a regulated pressure of 58, and the stock fuel rails regulat that down to a lower 5x psi.
