TBI Harness Rubber Grommet!?

[ShortBus]

Where can I find a rubber grommet for my throttle body injector wiring? The old one was destroyed beyond repair.
Should I just use some sealant and goop it up?

That’s what I did on a grommet for the ECM harness leaving the cab on another vehicle. Just goop it.

Its amazing how much better the throttle response is. Its like a whole new truck. That TBI unit had 200k on it.

Only snag after the rubber grommet was I had a weird buzzing from the firewall behind the glove box. Found a fuel line that was touching the firewall and got that fixed.
I'm going to replace the crappy tps with a good ac delco one and my next project is doing the plugs, cap, and rotor.
