Has anyone deleted their fuel pressure VSV on the 1FZ, and just run a vacuum line straight from the intake manifold directly to the fuel pressure regulator (FPR)?
I understand that the VSV is designed to control vacuum to the FPR under certain conditions (hot starting? cold starting? high vacuum?). Several other Toyota guys have deleted this system entirely to simplify the vacuum routing and the fuel system. Just curious if anyone has done it on a FZJ80 and what their experience has been.
Thanks!
