Does anyone think it would be ok to wire wrap some extruded hose with aluminum and bend it into the shape of the preformed unit and use that instead?

And alternatively, does anyone have a list of Mazda part numbers for all the preformed vacuum lines?


Thanks,

why don't you just buy the silicone like everyone else does? its proven to work and with the plethora of colors they are available in, you can personalize it all you want... sh*t you can color code by O.D. if you want to. hose technique's webpage

I have Viton hoses ready to go.

But of course they don't include the preformed units. I would like to avoid mixing materials so the possibility of adding wire to make the preformed units out of Viton 'sounds' good.

But thanks for the info.

if you cut the hoses a little longer (10-25%) than the stockers, you should be able to get them to fit in place of the preformed ones with no issues. sorry, i misunderstood what you were saying earlier... it read to me like you wanted to make aluminum vacuum lines

Cool, I hadn't really thought about just cutting the hoses longer...sounds like a simple and easy alternative.

Aluminum vacuum lines, I'd love to see a full set of those on an FD!

Thanks!

i think they'd look damn sharp, especially if someone went the extra mile and had them all polished or annoidized.

and just think you wouldn't have to worry about replacing the damn lines either, and less worries about a vaccum leak.

hmm..hard vac lines. I'm actually surprised no one has done this yet.

Doesn't gain you anything. You still have to use hose at the ends in order to make the connections to the solenoids, nipples and hard lines. In fact if you remove one rubber vac hose and replace it with a hard line with rubber or silicone hose on it's ends you have just replaced a hose that originally had 2 connections with one that now has 4. I don't see how that's an advantage.

Just leave the preformed ones alone. The silicone lines will kink when you try to twist them and they are thick but just too soft. I don't know if the Viton will kink though.

viton kinks and split just as well as silicone hoses.
I have had mine for two years, and there has been three instances where the hoses kink(near the turbos) and hose split(both times out of solenoid)

Wait Wait!

There are hoses made of Viton and other compounds, which could be any percentage of Viton...and there are 100% Viton hoses (which is what I have). They do not appear to have any issues with kinking or splitting. Of course I might be wrong.

silicone rocks.... yes it is soft...but can resist heat much better

The viton made by HighTempSilicone is damn thick and sturdy. You can make it kink, but you have to really squoosh it. It can split, too but you have to scratch it up and then yank on it for a while.

I just did my hose job and if anyone's interested I can mail them a couple of scrap pieces if you're curious.

Why go to viton if it still splits?

rotaryhardcore

DamonB...

The 100% Viton hoses do not have the splitting problem...splitting them is like splitting a piece of standard rubber hose.

The viton I have is not likely to split in any way.

PM me if you want me to mail you a piece of the viton tubing. My only reference is the worn out silicone and neoprene rubber that was on my car. I'd be curious what your opinion is on it.

I just did a silicon hose job. As mentioned above, some hoses need to be cut a bit longer. In addition, you can bend some the hard lines (i used a steel punch) so that your new lines will be less likely to kink.

High Temp Silicone

Viton has a much higher tensile strength compared to silicone. It is possible to make any rubber material split by cutting the wall along the centerline of the hose and applying pressure in opposite directions pulling it apart. The thicker the wall the harder it is to split. The chances of our Viton splitting on its own is 0%. If you try and try hard to make it split it will happen only if you cut the side wall first.

Another advantage of Viton is that it does not degrade in the presence of petroleum oil whereas silicon will.
It is more chemically stable in the presence of the usual fluids usually associated with cars than silicon. Naturally I bought silicon lines several years before I had heard about Viton.. Oh well, live and learn I suppose.

wrankin

I did the full vac hose replacement with silicone. I did not have any problems with lines kinking if I cut the offending lines slightly long. In fact, I cut every line slightly long and trimmed them to fit when installing them. There are several lines that need some special attention:

1) there is a long preformed line that sits under the UIM and connects two solenoids. This is the line which tends to get piched when re-installing the UIM. Cut this line fairly long and then you can fold it out of the way when putting the UIM back on.

2) There is a U-shaped line that sits under the pressure tank. The tank tends to pinch this line. Cut it about twice as long as needed and then you can fold it flat under the tank without pinching.

3) If you cut the two pressure tank lines long it is much easier to move the tank around when you need to get underneith it.

Hope this helps,
