Most of the time, the cause is an old rubber line that has gone hard, brittle, split or loosened from heat and age.\u003c\/p\u003e\n\u003cp\u003eExoracing black silicone vacuum hose restores a clean, airtight path for the signals your ECU, boost controller, wastegate, MAP sensor and gauges rely on. It stays flexible in the engine bay, resists ozone and UV better than standard rubber, and gives the bay a tidy black OEM-plus finish.\u003c\/p\u003e\n\u003cp\u003eUse it anywhere you need a reliable vacuum or low-pressure signal line. Do not use standard silicone vacuum hose for petrol, diesel, oil or brake booster lines. If you need to route the hose near heat, use Exoracing silicone fibreglass heat sleeve, Exoracing Velcro heat sleeve or Exoracing heat reflective tape to protect the line from radiant heat.\u003c\/p\u003e\n\u003ch2\u003eWhich Hose Size Should I Choose?\u003c\/h2\u003e\n\u003cp\u003eMatch the hose inside diameter to the fitting or barb outside diameter. The hose should push on firmly and seal without being loose. If the barb is between sizes, choose the smaller inside diameter for a tighter fit and use a clamp where needed.\u003c\/p\u003e\n\u003ctable style=\"border-collapse: collapse; width: 100%; border: 1px solid #d8c4e8;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 25%; padding: 8px; border: 1px solid #d8c4e8; background-color: #4b1f73; color: #ffffff;\"\u003e\u003cstrong\u003e\u003cspan style=\"color: #ffffff;\"\u003eHose ID\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 25%; padding: 8px; border: 1px solid #d8c4e8; background-color: #4b1f73; color: #ffffff;\"\u003e\u003cstrong\u003e\u003cspan style=\"color: #ffffff;\"\u003eApprox.
