Green vacuum modulator question
I’m replacing my vacuum modulator on my 1989 F-250 XLT Lariat 4x4 with a 460. My auto parts store only had a green stripe modulator. Is this sufficient? It appears that the original that is still installed is a black stripe.

I doubt it will make much difference and should be fine
When Ford had 20 different vacuum modulators back in the day, the aftermarket only had one or 2
The green stripe was the high altitude one IIRR
