I finished restoring the D-Jet EFI on my 73 2.0L and fired it up. It runs!

However, I have a few questions about routing the vacuum hoses.

1. There are two vacuum fittings on the distributor. A 5mm fitting on the near side (toward the distributor) and a 3mm fitting on the far side. The 5mm appears to go to a connection on the far side of the throttle body. Where does the 3mm fitting go? I've seen pictures that show it going to a fitting on the near side of the throttle body, but there is no fitting there on my car.

2. There are two 11mm vacuum connections on the side of the plenum toward the battery. Where do these go? Does the connection on the oil filler go to one of them and the decel valve to the other? I've seen pictures with a "F" shaped rubber fitting on one of these connections. Is that fitting needed? If so to route to where?

Thanks,

----Bill

The factory put a hose on the vacuum advance port, but just left it sitting loose on top of the engine, strange but true.  The 11mm ports would be for your decel valve (if you have one, I don't and the hole is plugged), there is another and I believe that goes to the PVC valve at the base of the oil filler neck.

Travis is absolutely correct on all counts. The fact is the later 2.0 did not use vacuum advance, just retard.

I tried to run a 74 2.0 through smog in CA once a few years ago. The factory ran that advance hose up near the TB and left it laying there. The more anal SMOG tech must see a hose, or they will fail you on a visual.
