It's been a challenge trying to save a pair of tubes.
I taped up the holes in the head & soaked one tube in vinegar for 2 days. Then 2 days in Evaporust. Now 1 day in Phosphoric and it will not budge.
Any bright ideas??

Worth a try but nfw. For my next trick, let's try diluted CLR & see what happens

You could also soak the entire head in full strength simple green.

I think b-man's "hammer on a c-clamp" idea is probably your best bet. Soaking in full strength Simple Green or something similar may help too, but if they're really rusty a little love tapping is going to be required.

Been a long time...iirc I pulled freeze plug and used a brass drift to tap them loose. I think it was just the taper not corrosion.

Have you removed the plug at the other end of the head to do some "loosening" from both ends?

I gave up.
Soaked overnight in Vinegar & the solution came out as clean as it went in.
Tried diluted CLR & pretty much the same thing.
Next was Muratic acid which got a ton of rust out and cleaned things up pretty nice but there is a great deal of rust present and I am not sure that the heads are worth saving, much less the tubes

[BruceWilkie]

Did you remove the freeze plug at opposite end? If not, do so.

Then use a round squared edge of a punch or rod and place the edge against end of the gusher tube and hammer the tube loose.

Its a tapered tube and takes little effort to press it in. Takes alot more effort to "un-press" the fit. Add years of galvanic corrosion and even harder to break free.

However once it cracks loose it practically falls out.

The vinagar and water solution isn't an overnight deal, probably should have let it sit at least a week. Ive cleaned other parts with a 10/1 and let them set a few weeks

Apparently there are 2 different style tubes and they may not be interchangeable?
Do any of you know the breakdown in years?
Note the tube on the left, it has a different shape & the top is a little taller & the right hand one has more of a rounded top.
