Hey guys, installing some BOVs soon and thought of refreshing the engine a little by replacing some of the silicone hoses.

I don't have space to remove the bumper atm, so I only want to replace the silicone hoses that I can reach with just the hood open, if i've missed any possible hose parts.. please let me know.

I need help finding the correct size I listed below + finding the right place to sell the parts. I know most sell them as a kit, I only need what i highlighted below, some in blue, some in red. Any help would be appreciated.

A: throttle body coupler size? I found options in link below but don't know what OEM size is (3"x3" or 2.75"x3 or...)

B: BOV vacuum hose diameter and length? (4mm, 6mm or 8mm?) I believe the length is 1" correct?

https://www.z1motorsports.com/vacuum-hose/z1-motorsports/5mm-silicone-vacuum-hose-p-4933.html

https://www.z1motorsports.com/vacuum-hose/z1-motorsports/8mm-silicone-vacuum-hose-p-9790.html

C: coolant tank hose. I found this part that comes with a kit, i don't need all the kit part so was hoping to buy it separately. Will this reinforced hose work? .. any link to where i can get this?

D: Upper radiator hose. I was only able to find this part (without having to get a whole kit).

are you referring to the hose sizes? they're all standard OEM sizes and fit really well with the stock pipes.

Here's what I got from Concept Z, including the part #s

i was wondering, did you ever have any issues with your cooling fans behind the radiator? i found out i may need cooling fan motors because both my fans stopped working. and i checked the fuses etc.

Hmm never had that happen. Not sure why that would happen.

It did happen to my 68 camaro once , fans stopped working due to a bad alternator

thank you, how hard was it to install all the new hoses ?
The throttle top pipes are easy. The hard pipes are tricky with the bumper on, and most probably you’ll end up loosening the fmic hoses with movement = boost leak

So do it with the bumper off
