Hi new here. Been building stuff all my life but this is the first factory injection one I've dealt with.
89 suburban 4x4. 350 w/90 camaro tpi. Headers. 113 heads. 1.6 roller tips to bring the cam up to par. Howell prom set for a zz4. Harness rebuilt and prom reflashed for Speedo. No smog nor egr as I no longer live in the people's republic of California.
About to stab dizzy, run the valves etc...when I get days off. Can't seem to locate a vacuum diagram that is for a non egr non smog tpi?
After that I remove the th400/transfer case and replace them with a worked on 4l80e compushift, gear2gear transfer case.
Thanks for any info or advice I can gain.

i have a 91 z with no egr or smog that i removed and off the top of my head i got a line too the fuel reg, one that goes around too the black ball on the drivers side that supplies the cruise, one that goes too that weird heater hose set up on the passanger side and one that goes into the firewall that supplies the heater control. so depending if you have cruise or how ur heater controls are set up in the suburban you might just need the one that goes too the fuel reg
