I have a duel vacuum port advance unit on our 2.0. Can I ditch it and use a single port unit?
I think the second port is a decal thing for emissions right? Stock injection, tracked a vacuum leak and poor fuel mileage to the vacuum advance unit. |

All of the vacuum canisters for the distributor had two fittings. For many of the 74+ cars, the advance fitting was simply not used.
You can use whichever ports you like, but the engine would probably run best with both the advance and retard hooked up, as it was in the 73s originally. --DD |
