just like the title says.... what is the standard size?

 

I thought it was 5/16?

 

I want to say its 5/16 also.

Shoot 860 Performance a PM, Vinny did mine.



Dave is showing 3/16" tubing for sale at Nitrous Outlet for DP applications.

 

different kits & styles use different sizes. 16 fogger lines are smaller than some of these monster plates. PM some of the sponsors and tell them what you're trying to do, so you get the correct balance. Good luck.

 

We use 3/16 on the hardline from the distribution block to the nozzles on a directport.
We use the same 3/16 on a single nozzle or efi plate from the solenoid to plate/nozzle.

On the fuel delivery from the shrader valve to the solenoid we use 1/4.
Feel free to get in touch with me to tell me exactly what you are doing and Ill tell you what to use.

i'm running the holley powerpro plate kit, just wanting to hard line some of the feed lines and the purge. wasn't going to hardline from the fuel cell to the noid.

 

Wich system is that? I do not see a power pro.

well heck, hang on i'll check. i thought that was the name of it. i bought it from you. its a 4150 flange single stage plate kit 100-500 comes with 15# bottle. pro power (PN: NX-50040-15)

 

Ohh I got you. I thought when you said holley it was a NOS system.lol

On that system you can use 3/16 from the solenoids to the plate.

btw, i meant 3/16 not 3/8 (that'd be a BIG n2o line) i don't know why i put holley system.
