Fuel Rail and Plenum Cover Removal


The Best of Corvette for Corvette Enthusiasts

I took off my plenum, fuel rails, and coil covers...
I Need to find the name or part number for the zip tie anchors that hold the wire harness to the fuel rails. I broke half of them. They did not "wiggle" out as suggested. In retrospect, I bet it would have been easier with a warm engine. Maybe they would have been softer.
Also... like many others, I broke the edge off one of the little wings on the Z51 line that goes into the coil cover on the passenger side that everyone complains about. It was just the edge, maybe 1mm, but enough to **** me off. Again, Im sure a warm engine would have made it easier. I saw that part number before, but I cant find it now.
Questions:
What is that line for? What is its function? It was a little oily when it came out. Also, Im asking because I forgot to put it back on and I took a little spin around the block to make sure everything was running good. No Problems at all. I put it back in, and drove again... no difference.
Also, the screws I had to remove to take out the coil covers do not come out of the covers. I was afraid I was going to drop one so I had a magnet on it while turning. It would have been cool to know they wont fall out ahead of time. Should they be forced out somehow before they are painted? If so... HOW?
Thanks in advance.. If anyone wants to do this, its pretty easy, but I highly recommend a warm motor.

The fuel rail covers are just snapped in place using a rubber grommet style fastener. Start of by lifting upward more towards the plenum side and they will unsnap without using too much force.

Then, once you remove the fuel rail you will notice a wiring harness that is fastened to the plenum cover. They are just zip ties that are snapped into the plenum. So if you wiggle the zip tie upward, it should slowly come out. Sometimes a tool is needed to get this started. This is what it should look like once removed.

The next step is to remove a total of four 10mm bolts that hold the plenum in place. These also have a nipple at the top in which your fuel rails snapped into.

Lastly, there is one wiring connector that will need to be disconnected in order to lift the plenum off. Once this is done, you are ready to lift the plenum off.


Reverse the steps to re install everything. If you have any questions, feel free to pm me.

I have pulled on them and they will not come out. They look like serrated plastic fasteners.
