I have a LSA swapped C5 with a ZL1 Lid and HX. I want to run -10 lines for the whole Intercooler system. Is there a slick way to convert all the Inlets / outlets to -10? I already have the brick / lid fitting in -10. I need to convert the pump, HX and maybe a Maggie (top of Battery) Tank. That tank is rough plastic and a 'compression' style fitting might not seal well.
It is a street use car so I really don't need the fat -12 lines. Plus there isn't a lot of room for anything at all. If I can minimize a few things it makes a big difference in the cleanliness of the Engine bay. IMHO...
Any suggestions??
Thank You!!
They make female -12 to male -10 just search ebay its probably like $10. Your gonna reduce a good amount of flow be reducing the line diameter, id recommend staying -12 because you want all the cooling you can get even if its a street car
Thanks for the reply - I know it will reduce flow... Thanks for not Flaming me!
I saw a very cool fitting once that used an O-Ring but it was a compression type fitting that did what I need. For the LIFE of me, I can't find it. I think it was aeromotive but searched there and - nothing. They were like $20 each! but a real problem solver. Only IF you had a smooth wall tube. Won't work on molded plastic.
I could use a short chunk of 3/4 hose and put an adapter on it with 2 clamps - that would be ugly though. I don't want more ugly.
Any other info suggestions??
Thanks again!!
In this type of situation, I usually look up all the various available adapter fittings on amazon, then search for the name brand equivalents when I find the ones that will work. Then again, you are dealing with unpressurized water instead of fuel, so generic fittings may work for a lot less money. And as much as I like shopping at Summit, stay away from their house brand AN stuff. I have yet to get a Summit branded AN fitting that does not leak.
It's a good idea and keeps things looking clean. I am really not worried about going to -10 for the Intercooler system. I'm not cutting anything off so I can always go back to -12 if it becomes a problem. Thanks for the help - love this place.
LS1RX-7 - My son & I did a 93 with an LS1 / T5. Fun project. It was my introduction to the LS world - Now look at me! Sticking F'n Superchargers on em. I'm Old Skool though ... Everything MUST have something sticking out of the hood AND be Tubbed. I'm only 1/2 of that philosophy on this project. Tubs might be coming some day... And long gone are the days of tuning with a screwdriver.
Practice Hood - GLAD I got it. The -10 lines will be easier to hide. The intake tube is going away too.
The -12 in the pic is rubber Push-Lock. The -10 I will use is Braided Amazon China stuff. I'm only using it because it is NOT fuel and NOT pressurized. PTFE is not needed for my intercooler run.
Like they say in the NFL... 'Upon Further Review' ....
The reason the AeroFlow are $20+ is because they ship from Freak'n Sydney Australia! They are under $9 on their site. RaceTronix has a similar fitting - shipping from Canada!- For the same price but shipping is tolerable.
Thanks again for all the help here - Eh'

You don't need ptfe but the outside diameter of -12 would be comparable to the -10 you are putting on. So you could keep the flow of the -12 but have the size of the -10 you want.. Amazon has ptfe braided pretty Cheap And I have used it with good results.
Just a follow up. I got it done and bled - no leaks either. The 10AN T with the cap is the high point and I used it for filling - I don't have a reservoir. What ever is in the system is what I have for cooling. It's not a race car so I'm not really worried,
The Hose Barb / AN conversion fitting works if the barb is cut off. The O-Ring acts as a compression sleeve and it holds surprisingly well. Not gonna be a problem at this point.Cutting the barb off the ZL1 Heat Exchanger showed the ID of the Inlet / outlet to be just over 1/2" so the 10AN hose (or ANY size) is limited by that. Here's a couple pics.
I'm happy with the way it turned out AND I can get rid of that UGLY tube showing thru the hood 10AN is easier to hide. ZL1 Outlet tube - that's as big as it gets!
