Where can I find a replacement tube - or fabricate one - for my 1995 Buick LeSabre, VIN L engine? I broke the tabs on the twist-in fitting at the top. I was replacing the upper intake manifold (UIM).

I can see I also need to replace the pressure regulator, probably the EGR valve, and a couple of the plugs on the wiring harness that fractured when I removed them.

I plan to go back in and down and replace the lower gaskets as well. I had hoped to get away with a quick and dirty fix with just a new UIM, but got tripped up). Any other parts to replace that you would recommend?

What is the torque for the bolts in the UIM? The factory shop manual does not seem to give that.

Thanks for the help.
