Can someone tell me what is the latest source for silicone vacuum hose kit? All the links, except for hiperformance, are dead... would prefer to pay less if there is an alternative source.

Thanks~

Before buying silicone hose, you might want to check out this test of various hose materials using oil at 240°F to heat the hoses. I went for Viton and have never regretted it. The sole disadvantage is that sizes are (were) only available in inch units. That resulted in very tight small hoses and somewhat loose larger size hoses. But the stuff just lasts and lasts, and stays flexible.

Although the article targets hose material responses to hot oil, the high temperature could easily be the main stressor.

So is the hiperformance kit a go? Any issues with them? If I bought the silicone from seven1997's link, what lengths of dimensions would I need to buy if anyone would be so kind!

How long of each size? More than enough is better too.... Anyone?

"I'd say minimum 20 feet of the 3.5mm, and 5-10 feet of the 6mm hose. You'll want more 6mm if you have a boost controller." -Dale Clark

Yes, thanks. I saw that after I posted the question. But I like the info Jim gave, aka SGTBlue.

I'll second getting Dale's check valves and HT silicone. Been running both now for a few years with no issues. The valves are one of the best bangs for the buck you'll find. And I think it was his prior posts that made me decide on HT silicone over Viton. I have no regrets and kept about $200 extra to spend on other stuff.
Unfortunately HoseTechniques no longer offers a "kit" for the FD...which included all the needed lengths and sizes for a full sequential system WITH emmissions. FWIW as a reference, these are the lengths they offered back then in the kit. But if you have deleted emissions, you'll have lots left over.....especially of the 3.5 size.
40' of 3.5 mm
15' of 4.0 mm
16' of 6.0 mm
4' of 8.0 mm

I will disagree on problems keeping the colored hose looking nice. My red ones still look fine going on three years. If I do get some dirt or grease on one (usually from grabbing them with dirty hands) I just wipe it down with a little window cleaner on a rag.
