Tired of busted vacuum hose (aka spider)

You could flair the hard line to help the ends seal.

I thought some one recently posted up about finding the hard plastic tubing and the end fittings at a local big chain parts store, maybe AutoZone? They said the tubing was in rolls and the fittings were sold per piece and all the stuff was filed under "emissions" parts....not make & model specific, but in "generic" like the stuff on the "Help" display.

The OEM spyder on my car was 17 yrs old but only 7400 mi, and had no leaks when I tested it. That was back in 9/05. The replacement copy I bought has been in since then and has a lot of miles & very little time, almost 27k miles & 4 yrs, and still holds vacuum.

I was thinking about using regular vacuum hose before I bought the replacement spyder and eliminating the fittings by going directly on the nipples. To keep it off of the hot metal I was gonna use spark plug wire looms.

Discount auto carries hard plastic lines in rolls and sassorted hard rubber fittings that looked more elastic than factory stuff.

My only concern is hard plastic will degrade w/ time and temperture like the factory tubes.

With out having removed the plenum yet, I don't even know whether its a seal issue at fittings or cut line.

I will find out soon.

also check the ck valves they have a tendancy to fail
