Wongs: I'm far from an expert on this, but ND (who has excused himself from this discussion) is technically correct in that the hose itself does not thread into the reservoir. But, it appears that what is called the "Quick Connect" in fact does. You can see this on the photo, where it is being removed with the box wrench from the reservoir. The hose then connects to this. I assume the hose threads to the Quick Connect. Anyway, once again, good luck with it.

Thanks for sticking with me old coyote. I explained in my second post that I was wrong, that the pressure port in the pump was in the pump that was accessed through a crircle that was cut out of the reservoir. Anyway, put it back toghether tonight and threaded the fiting on the new hose into the pressure port on the pump (after I found the spring and reinstalled in) and was in the process of bleeding the systme by jacking up the front tires and turning them back and forth, then topping of the fluid and it was working then all of a sudden it blue the hose out of the fitting that was on the house. This came as one piece with the fitting pressure fitted on the metal part of the hose. It is like it blasted in out but i'm not seeing what was suppose to hold it in when it was put under pressure. More help would be appreciated.

Sorry, I don't quite understand what happened. Do you mean the rubber hose came out of the metal sleeve that it goes into? You say it "came as one piece with the pressure fitted on the metal part of the hose." Sorry, but I don't follow. I know it's hard to explain these things sometimes without being able to just show people.

Breakdown the hose into parts in an effort to be on the same page.
Flare- the 'bell' on the end (sealing surface)
Tube Nut - the threaded part ,should spin freely on uninstalled hose assembly
Tube - metal section.
Crimp - sleeve with two sets of integrated barbs (hidden after crimped by machine)
Rubber hose- self explain

OK, I think I got it now. The fitting that is at the left, on the end the metal portion, stayed in the pump and the metal line cae out of it...yes? If so:
I can't tell from the photo if that fitting has threads on it. Was that fitting threaded into the pump (that is, into that connector that we talked about earlier, that threads into the pump)?
If so, then obviously the line should be flared on the end so it's impossible for it to come out of the fitting.

Now if the tube nut is still threaded into the pump, (which is how I took it) and the tube came out. the hose assembly failed. The flare was faulty.... if the hose separated from the crimp . It was either not inserted over the barbs enough or an incomplete crimp. both ways- defective hose. Find your receipt.

If it's a threaded fitting, it would have to be flared. No other way to keep the line in there, an it's not the threads that actually seal the fluid in. Tightening the fitting presses the flare against what it seats on. You said earlier you changed this hose. What about the old one? Was it flared and did it connect in the same way as the new one?

It's possible that what you have here (or should have) is an inverted flare, which means instead of an end that is spread to fit over a rounded seat, you have an end that first spreads and then closes in, so it's basically rounded and then fits inside of a flared seat. Sometimes, the inverted flare is created by putting a fitting on over the end of the tube, and that can fail, causing the fitting to come off the tube, under pressure or even before installing if it's especially faulty. Check it against the old one if you can. And, as xk says, if it's faulty take it back.

I've been on both sides of the counter, so, bring the tube nut, hose assembly, receipt and box back. Make sure the hose is clean and dry. A puddle of tranny or brake fluid on the floor or counter is the first thing to **** off your parts guy. Make sure the new matches the original.

Coyote, I believe that hose is a Dorman product, they usually provide an actual double flare on the tube. unless they farmed it out. But, I am seeing a pair if orings in that Napa pic along with yellow protective cap. The double invert is on the sector end. JIC 37° IIRC. Is it possible, with the tube nut tread being the same, that mismatched fittings could have damaged it enough to allow failure???
