    you can use a 5/16" and 3/8" compression fitting adapter or Duckysbht posted the PN for the quick connect adapter fittings in his NBS V6 to LSx conversion topic.

    the fittings on the fuel filter are the same as on a fuel rail. On the inlet side is both a 5/16 and 3/8 fitting and on the outlet is the same 3/8 fitting as on the fuel rail only its the female side. Dorman sells all three of the fittings in a generic type connection for use with hose and clamps.

    To add to this becasue i will be using the corvette fuel filter and therefor will not have the fuel pressure raised when the engine vacuum changes will i be able to start it and drive it with out doing tuning to the PCM, i don't have the money yet for a tuner and have already sent the PCM out to get VATS and the trans code removed so i don't want to keep sending it out

    It will probably be fat at idle and correct at load and high rpm since 58psi is about where they run at WOT and around 52 at idle. Put in some overtime and and earn some $$$ for a complete tune. Who did the base tune for you?

    it was brenden@lt1swap that did it for me. Hopfuly after the july shut down i will be able to put in enough overtime to pay for HP tuners. Thats if GM keeps making trucks, all we make is truck axles and drive shafts where i work
