Crossover tube O rings needed

[Drewstang]

I can't seem to find a local source for the o-rings on the crossover tubes. Local Ford dealer says they are not replaceable, and it looks like they are 27mm x 1.9mm in size. I don't want to buy new tubes just for the o-rings. Any ideas?

I have a universal O-ring kit in my garage. I will happily throw some in an envelope and you can try them.

I've got an o-ring set from Harbor Frieght, but all the large diameter sets are 3mm thick. The stock size looks to be 27mm x 1.9mm but no one around here carries them.

Did you read post 2?

Yes, they can get them here tomorrow but I want to have it running by tonight.

New o-rings on that tube will make it difficult to install the first time. I know this from experience.

Go to the hardware store. The only difference between factory orings and others is the fact the OEM's are flat. The rings from the hardware store will be a little harder to get in, but they go in. Coat the ring and tube in black rtv and you will be set.

Isn't the whole point of using o-rings to elminate the need to use RTV silicone, since it's very difficult to remove rtv without damaging aluminum? I'm no expert, but I would have thought some sort of lubricant would be a more appropriate choice (such as propylene glycol, engine oil, petroleum jelly or dielectric grease).
