Manifold Vacuum Rail

OK! So last post was positive, engine started up, ran well and idled nicely. But that didn't last long...

While getting the tune sorted, I noticed that the vacuum readings were a little off and it turned out to be a vacuum leak due to a hose not being connected properly. Fixed the vacuum leak and then the engine didn't want to idle anymore... So I fixed the idling issue but that resulted in my brake booster not getting enough vacuum to assist the brakes 🙁

So the real problem was the vacuum set up, I think. So I've come up with a set up that mimics a few other off-the-shelf ITB kits. Haven't had time to finish everything yet, but will post update when I get it running again and report back on the vacuum set up.

These are the push-to-connect fittings I'm using, swivel tee fittings.

Marked out the holes and drilled 11.1mm holes so that I could tap a 1/4" NPT thread.

The fittings tested fitted and measured so I could cut the hoses. The hoses need be installed in the fittings while they're out.

Vacuum rail installed and the old holes plugged up.

Also test fitted the filter backing plate, some clearance issues here...

Installed a Garage Star Wiper Cowl panel, and need to make a new fuel hose because I had to go from dual to single feed fuel setup.

And finally installed and gapped the headlight covers, hate doing them so much.
