Just FYI for anyone considering the Mishimoto catch can kit. The can bracket will not fit on 2018 370s. Not sure about 17s but Nissan changed the design of the expansion tank for some reason.

what size diameter hose is the generic Mishimoto amazon can and also the crack case end? are they the same hose diameter size?

Also what is a good hose material to re place with?

I used braided SS lines for bling factor. -8AN I believe.

I got my ss hose from Jegs along with the AN fittings. The hose and fittings will cost more than the catch cans.

Does the "an" matter? How long of hoses do i need?. A link would work best, jegs website doesnt seem to work for me. Thanks.

If you want to use braided stainless hose. You should use the AN fittings. I don't know what size your cans are. On mine, I use -8 hose.

I got the same amazon cans as Mlsully. I was hoping to find the same or similar hoses and fittings

I don't know what the thread size is in the can. If it's like mine. I have to dig through some papers later tonight.

I had to log into Jegs to find my old order. Here's what I used.

4 of these. These go into the cans.

very helpful thank you. 4 hoses right?

One 10ft hose. You have to cut it to length you need for each section.

Have you ever worked with braided hose?

No first time

The braided hoses don't flex real good. You can't make sharp bends with it. To cut the hose. It's best to tape up the spot with lots of electrical tape. Then cut in the middle of the tape with a cut-off wheel on a die grinder. Don't use a hack saw. You'll tear it up.

You will need this to assemble the hose and fitting together.

Another thing to keep in mind with SS braided hose - be careful how they are routed and what they might be touching. As things vibrate and the motor rocks under torque, a SS braided hose laying against a soft rubber hose will eventually start wearing a hole into the rubber hose.


I went with silicone hoses for my cans.
