Just buy the hose techniques kit. It's been on clearance at mazdaformance for $49. http://www.mazdaformance.com/Merchan...egory_Code=470

you get way more than you need so you have some for emergency situations.

 

well i dont have emissions. like anything. so i dont want to spend too much

 

All you should have left is the FPR line, fuel injector bleeds, oil nozzle bleeds and wastegate hose. A measuring tape is your friend...

 

fpr is fuel pressure relief? and im running premix so no more oil injectors

 

I purchased about 25FT, and still have like 8 FT left, however most of it was used for the boost gauge!

 

Yeah, once you get rid of all that crap, you don't need much.. I think I got 1 foot of 10mm for the brake booster hookup, 6 feet of 8mm for the larger lines and Fifteen feet of 6mm and I used it all... but most of the 6mm went to the boost controller. WHen you get rid of the emissions crap, you can also buy a lot less vac line!

 

Fuel pressure regulator. It's mounted on the secondary fuel rail, and it's vac line should be connected to the angled nipple on the inside of the LIM.
