Trying to remove my intake to install the new Oil Pressure Sensor. I think I have everything off, but there are two stainless steel braided hoses that go from near the driver's side firewall into the intake on the driver's side. I don't know how to remove these. They don't pull off nor do they unscrew.

Anyone know how to get these off?

Also, the 10 8mm hex bolts that hold down the intake all came out except the two back ones. I can't get enough clearance to pull them out. I tried lifting them (the bolts) as high as I can so that I can pull the intake forward, but it doesn't feel like I have enough clearance on those two long bolts. Argh.

Any help would be greatly appreciated. TIA!

Here's a pic of the hoses:

 

Have you tried reading over at LS1Howto It has great instructions on removing the LS1.

Cheers!!!

 

use a fuel line disconnect tool to remove the braided lines. Astro Pneumatic Tool company makes a nice set that you can obtain that accomodates a number of varying sizes.

As far as the intake bolts, they need to be loosened and then lifted one side at a time as you angle the manifold off the engine. They are difficult in the fact that they obviously don't want to stay in the lifted position. Just lift the bolt and with a simultaneous movement twist the manifold silghtly away from that bolt hole. Do the sameof the other bolt on the opposite side and then remove the bolts entirely once you clear the firewall.

 

On the rearmost 2 intake bolts, I loosened them and lifted them high enough to get a small amount of duct tape to hold them in a suspended position. I did the same thing reinstalling my intake. It really isn't too difficult. Hope this helps.

 

Thanks, I did follow the LS1howto instructions but I think most of their instructions is in relation to an F-body. The instructions don't mention those fuel lines at all nor are those lines in the pics.

 

You can buy a cheap set of plastic fuel line removers at any auto parts store. I also use tape to hold up the last two bolts. As far as remving the lines, you take a tool that will resemble a cylinder. Mine are plastci "C" shaped things that you snap over the line. Youpush it into the line and it will pop the spring clips inside so you can take the line off. Be careful, a crapload of fuel will spill out so put a rag there.

 

If you exercise a little caution, you don't need to remove these two lines from the fuel rail at all if you don't want to. After pulling up and disengaging the injectors, just bend them rearward and use some some string or a long wire tie to secure the fuel rail assembly out of the way.
I would recommend you pick up an inexpensive set of fuel line removers since you can also use them for you fuel filter, etc as well.

 

You don't have to remove the braided fuel lines for removal of the intake manifold, if you pull the injector rails out of the manifold first, however, if you prefer to remove the fuel lines, here's how to do them.
The braided lines as stated before are fuel lines. You will need a fuel line disconnect tool (available at almost any auto parts store). These are very simple to use. The tools are small plastic pieces that go over the hard portion of the fuel line;
1) determine the fuel line diameter and use the plastic tool designed for that diameter.
2) open the tool (the tool is hinged on one side, allowing the open side to expand over the hard portion of the fuel line)
3) close the tool over the hard line and slide the coned end of the tool into the braided connector
4) when the tool is slid into the connector ( a slight amount of force is required) this will contact a spring loaded clip for the connector seat (similar to a quick connect coupling)
5) while holding the spring clip open by the disconnect tool, yank the fuel line away from the braided line.
For reinstallation of the line, simply push it back into the braided line untill you hear a click. Double check to make sure the two lines are secure by trying to pull them apart.

P.S. there will be some fuel pressure inside these lines so, hold a rag around them to prevent fuel from spraying around your engine compartment.

I hope this helps.
