    If the fuel rail you have with your engine came with two feed lines it has a built in regulator. The 3/8" is the feed line from the pump and the 5/16" line is the return to the tank. If your fuel rail only has one fuel fitting you will need an external regulator or you can use the Corvette filter that has a regulator built into it. Wix 33737 is the PN for the Corvette filter.

    The EVAP can be removed and bypassed on vehicles that are not smog checked in strict states like Cali. If it's in a vehicle that was not originally equipped with an EVAP cannister then its not normally necessary in a transplanted engine setup.

    on mine has the 2 lines with the reg on the rail i use 2001 truck fuel lines they fit really nice so im gonna use factory filter the only line i need to make is the one from the back of the filter to the sending unit i was going to cut off the factory end where it hook up to the plastic line on the 2001 truck and just use F.I hose clamp to clamp it to the 87 sending unit but im worried the pressure will blow off the line i spose i could use compression fitting on that end though!!
    any thoughts???
