Hi Folks,
I have removed the (stock) injection lines from my '95. Unknown if they've ever been removed before. I sprayed some PB Blaster on them the day before. The nuts on cylinders 5 and 6 were tight and I had to use the wrench all the way till they were off, whereas the others could be turned by fingers once loosened a couple turns. Now that they are off, they still don't want to turn. In fact, I'm pretty sure I saw the sleeve turning as I turned the wrench -- there's a sleeve between the tube and the nut, which is supposed to be tight to the tube, not to the nut. So do I submerge them in PB Blaster and hope they loosen up, or did I likely damage the tubes and have to replace those lines?

The tube nuts should slide back and off the sleeve your talking about. They are likely full of corrosion and the cause of them not wanting to rotate. Keep working the nut by rotating and try sliding it back at the same time.

PB Blaster is okay, but I'll take Kroil every time.

Ok, I gave them a good soak and got them freed up. There doesn't *appear* to be any damage to the lines, but I can't see inside them or under the sleeves. Not going to worry about it, if they leak after installing, I'll deal with it then.
But now, since they've been soaking in PB Blaster and sitting around in my dusty garage, I assume I should clean them real well before putting them back on. How? Shoot some brake parts cleaner through the lines, blow them out with compressed air? Try to run some injector cleaner through the lines?

Meh, PB Blaster is just fuel......... I wouldn't worry much past a simple compressed air blowout.
