Hi guys,

I'm removing Megasquirt from my car. I removed the stock FPR during the install so currently its running a 1:1 FPR. I will also be putting back the 12:1 FMU.

Does anyone know what the stock fuel pressure is for a 99?
Is it a static fuel pressure or does it vary based on vacuum?


Thanks,
Ivan

If I recall, stock is around 50 psi. Unless there was a vacuum line running from the manifold all the way back to the OEM FPR, it is static.

Download the Service Manual PDF - there is a section on testing/troubleshooting that described what the limits were on the fuel pressure.
