So I just finished up installing my alky control meth system on my Z06, and wanted to ask a question.
The filter that came with the kit, it’s the filter and then two fittings on each side that are both -4 an male fittings. One of those fittings was damaged, so I went to the store and had to use a few reducers to connect to the filter to make it work. My specific question is, with the increase in diameter of my plumbing, will that affect the pressure in the system? Or does this look okay?
I teated everything and everything works, but I just want to make sure that I’m increasing the diameter of the lines like I have shown won’t result in a decrease of system pressure causing the nozzle not the squirt properly. Thanks in advance
Why not just call Julio at Alky and order the replacement parts so its back the way it should be. Those parts are pretty cheap. My guess would be somewhere around $20 or so.

I wanted to get the install done and the piece would have taken a few days for me to get so I just did it this way. I have a place that sells fittings and lines right around the corner from my house so I just went over there and they gave me what I needed. At this point everything is done and its working perfectly so I figure what's the point of taking it back apart and replacing the piece. I just wanted to make sure the change in diameter where I joined those pieces together wouldn't affect the pressure of the system, but it isn't and there are no leaks so I'm just going to leave it at this point.

How do you know it isn’t affecting the system or pressure? Just cuz its not leaking and still spraying doesn’t necessarily mean its all good lol. Do you have a wideband in the car to confirm its not running too lean at WOT? Just don’t want you to have any issues.

the turn on led light illuminated red when the system pressure is built, so if pressure wasn’t being built then wouldn’t that not light red? I also had the nozzle off the intake and tested it while spraying into a bucket. It sprayed hard and looked fine. I have already had the car tuned and I imagine if the car was mean my tuner would have seen it, but there were no issues while tuning.

also the original parts open up bigger in diameter as well don’t they?

let me explain it this way - If you have a 15 GPH nozzle, how are you certain you’re getting 15GPH output versus say, 12GPH now. The system will spray fine and look fine and the LED would still light up but you may be hurting the motor by it not getting as much fuel/octane as you’re supposed to have. Anytime you change plumbing for fueling, I would log it to make sure you AFR/Lambda is where its supposed to be. Never assume because the light goes red that its working as it should or that its spraying as much as it should..

Okay I'll call Julio tomorrow and have him send over the fittings. I already had my car tuned, so are you saying just by changing the fittings out now that I should take it back and have it checked over to make sure the AFR is good?

What I’m saying is a change in the plumbing size can either increase or reduce flow and that affects pressure and output. When you’re running a supplementary fuel system you should have a wideband O2 sensor and gauge in your car so you always can monitor how its running at idle and at WOT. You shouldn’t have to rely on going back to the tuner for him to tell you what your AFR is. But yes, good idea getting the right replacement parts. Either way, I’d recommend you still get a wideband and gauge for the future.
Don’t over think the whole thing, simply do a quick test, run the system for 30 seconds into a bucket and you should get 2 cups of methanol. If you get that leave it alone.
