I'm running a completely stock car, however I've had a vacuum leak CEL for the last few thousand miles, and haven't had time to work on it. Now I'm driving it again for the winter, and the fuel economy is just awful. I have a 1" crack on a hose that comes up from the engine near the alternator and makes two right hand 90* turns into the two hard lines right in front of the TMIC. Is this a vacuum hose? I don't want to replace all my vacuum hoses right now if I can avoid it, though I admit many are getting pretty hard though.
You can see the hose here, hugging the silver bracket.
Honestly, I should replace all of my vacuum lines. The only issue I'm having is there are Ancillary kits and regular kits, both of which are priced above 90 bucks. Not something I want to invest in if I don't have to. Anyone know the sizes for our hoses and if I'm lucky, how much I'd need to buy of each?
I spend all my time working on the Miata, and TBH the WRX engine bay scares me a little. But I'm not scared to get my hands dirty.
