After multiple visits to his shop and a totally frustrating experience dealing with my polisher, I finally got my parts back. Now it was almost time to do the final assembly.
But there was one major thing that still needed to be worked out. The alcohol supply lines needed to be reconstructed.
If you refer back to my "before pictures" in post #1, you may remember that I ran my stainless alky supply lines down the leading top edge of my valve covers using little home made straps bolted to the upper valve cover studs. Then I mentioned in post #14 that I removed them in order to make more available room for my coils.
Well, now it was time to rebuild them.
My alcohol tank and pump are in the rear of of the car. And from there, the alky is pumped to a splitter manifold on my firewall. On the manifold I have the filter and one-way check valve behind the cover, and a gauge, transducer, and two outlets to transfer alky to the intake pipe.
This is from before. All this is fine and can stay as is. But the two supply lines coming off the manifold had to be reconfigured. See below.
I always liked the way I had run the alky lines. I didn't want to change the general direction they were run previously. So I decided that they would go in the same direction as before. But I would have to lower them into the valley to keep them under the coils. But in order to do this, they couldn't be strapped to the valve cover studs any longer. Instead, they would have to pass through the coil bracket tabs. And unlike last time, they needed to be done in two pieces.
The first thing I did was bend up two lines leading from the manifold to the back of the valley. This puts the flare fitting in a good spot in order to facilitate removal and reinstall. Then I needed to fabricate a section of alky line that would
permanently be inserted through the valve cover coil tabs. Once the flares and fitting were installed, it would be non-removable. But this is OK because the fittings would easily be accessible when the coils are removed. Then this small section of alky line would just have to come off with the valve covers.
See below.
There was a lot of "Put-It-On" and "Take-It-Off" during this build.
Sometimes it feels like I'm living in the movie "Groundhog Day".
After this, I was ready to finally install the valve covers. As you can see, they are now polished. Just don't look too close. Someday, I will get them a little better myself. Funny thing though........It looks like a V-12! Because the reflection doubles the count of ignition wires!!!!
Here pictured below, you can notice the entire configuration of the alky lines.
Now I was able to begin finally installing the TR-6, wire harness, coil brackets and connect the valve cover vent hoses. I made some nice little straps to hold the vent hosing neatly against the firewall as it moves up towards the underside of the cowl. Also notice how I protected my wide-band XFI O2 sensor before it was installed. And there was never a need to change my dip-stick location so it stayed the same.
And before I went any further, I needed to test the alky system for any leaks. I temporarily installed the nozzles, powered up the car, and slowly applied a regulated 30 PSI to the MAP sensor. I watched the alky come on strong and the gauge max-out as it sprayed into a couple of plastic beverage bottles. While this was happening, I inspected and double checked every fitting and connection from the pump to the nozzles.
All is good!!!!
See the brackets-harness, TR-6, and beverage bottles below. Wow, those bottles fill up fast!
