Vacuum hose too tight

I received the proper length of proper cloth-braided hose from GT Car Parts. This hose is what GT Car Parts has been selling for 15 years for the connection between the vacuum assist cannister in the front of the car and the intake manifold (with the one-way valve in-line near the manifold).

I spent all day yesterday trying to get the hose to slip over any of the fittings (cannister, one-way valve, intake manifold). I used silicone gel, heat, bolts to ream the hose, etc., etc., along with friends with long arms, scabs on the their knuckles, monosyllabic utterances, and tattoos that same something about "mama.."

I simply cannot slide this hose over these fittings. The hose has a wire skeleton that prevents expansion with heat (and is purported to prevent collapse under vacuum).

Has anyone used this hose with success? Any tricks up your sleeves? Help is greatly appreciated.

Pietro - thanks for the help.. Excellent idea of expanding the hose with ever increasing sockets, each held with clamps overnight.

However, I gave up and bought a different kind of hose. The stuff that GT Car Parts sells, is original looking, but I cannot believe that Antonio took this much time to install originally. Furthermore, in the future, should I have to replace it, I will be too old to go through this process. I won't remember where I left the sockets.

Synchro - I went to a specialty hose shop yesterday to try and get my cloth-braided hose on the fittings. They sprayed WD-40 all over the hose and fitting. Did not help. They sprayed WD-40 over the alternative hose that I am now using.

Your admonition concerning petroleum based lubricant versus soap is appreciated, but I suspect that the manufacturers foresaw that these hoses would be used in petroleum-rich environments. Can it really be that harmful?

Ken - I believe in heat. I use heat to accomplish most tasks. I heated the h.ll out of the hose, but it did not help. I usually heat hoses to slide on a tight fit, but the wire "cage" wound in the wall of the hose prevented heat-induced flexibility enhancement.

Thanks for the idea.

racerboy - unfortunately, that is not possible. It is impregnated (wound) within the wall of the hose.

Ken - I believe that it is the wrong size. It is what Dave and Bill sell at GT Car Parts - I trust them. They have been quite helpful over the years and if they say that this is the part (after several calls), then I believe them. However, they qualify their answer by saying that, "...this is the only part available..." Hence, it likely is not exactly the right part. Another millimeter diameter size would be welcome.
