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 Edit: For future reference, it wouldn’t work without an adjustable fuel pressure regulator, the pressure would be too high (surprisingly). 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…
