when I bought my fd it had a gutted cat. goign back to stock and this part (check valve completely gone) bought the check valve from fritz but no hose.
Do you guys think I can replace the circled hose in pic2 with a silicone Akimoto hose will it hold up under heat and pressure

 

That goes to the air pump correct? If so, then yes, it'll work just fine.

You cannot use silicone hose for the section of hard pipe that connects to the cat. If you are talking about upstream of the check vavle up back to the ACV, a silicone hose will probably work.

I would think you could easily find that hard pipe for sale on the forum, lots of people removing their emissions.

 

I have both hard pipes just need the black rubber hose in the middle that I'm asking can I replace it with silicone

 

Sorry about that, yes it should be fine.
