So the pesky company that sell the boost gauge I bought apparently think that giving me about 10cm of tubing is enough to go all the way to my boost nipple on my EGR delete... Going to buy some red tubing off of eBay to do it all but just wondering if anybody knows what size internal diameter I need for boost gauge tubing? Also I don't know if somebody has made a list of the lengths and internal diameter of all the vacuum tubes in the engine bay so I could do those as well? 

 

Cheers

smaller the better air/vac travels very fast  you may also need a restrictor if the needle jumps around or long term it will wreck the guage

I used 4mm ID silicone tubing

Aquarium tubing

4mm
