    92 GSR fuel pump

    Does anyone know if I could just drop a 92-93 GSR fuel pump in my 90-91 LS? Would it be plug-n-play? I need it to feed fuel to my 98 Type-R B18C but don't wanna go crazy with new pump, regulator, and rail.
    Another option would be a Walbro 190lph, with stock regulator.

    What would you do? Thanks

    90 LS
    psi: 60
    flow rate: 33 gph

    92 GSR
    psi: 87
    flow rate: 54.2 gph

    98 type-r
    psi: 80
    flow rate: 44.9 gph

    I decided to go all out and get a Walbro 255, AEM fuel rail, pressure regulator, and gauge.

      Nice. Set the new regulator to stock pressure (or a little higher) and you...
