Replacement for bottom AB Valve Hose?

1) The bottom AB Valve (90 degree) Hose on my 1988 Pathfinder just split and I can't find anything to replace it with. What do I do? I believe this is part number #14864 (Hose-Ab Valve To Inlet Connector). I went to the auto parts store and they were not helpful. https://www.nissanpartsdeal.com/parts-list/1988-nissan-pathfinder/engine_mechanical/secondary_air_system.html?pnc=14864&diagram=148_B01

2) Also, the bolts (Part #16500A) that hold the air assembly to the engine are missing. What size bolts are these?

Thank you.

I've never searched for the hose before, but you can measure the inside diameter (ID) and just search " whatever the ID is" 90° hose and anything close to the size should work. Honestly I'd go slightly bigger if you can find and use some tighter hose clamps,  it's in such a tight spot, the only part I hate about removing the intake.  Mine cracked pretty bad several years ago, I have it just taped up so it's a looser fit and haven't had any problems. I could be wrong but I'm pretty sure it goes in before the filter anyways so if any dirt did get past wouldn't be a big deal, could still cause a vacuum problem though. 

 

I can figure out the thread tomorrow, my truck is at work under repair, I can yank it and see what thread pitch it is and let ya know.

So I can use any type of hose for this? That's were I was confused. I can use a heater hose, fuel hose, etc? Because I also need to replace the top Air Cleaner To AB Valve hose I'm looking at buying and cutting up this rubber fuel line as it has the same ID (1/2") - https://www.amazon.com/Universal-Molded-Fuel-Line-Rubber/dp/B07YLXS7C3/ref=sr_1_13?dchild=1&keywords=1%2F2+id+hose+90+degree&qid=1609466767&s=automotive&sr=1-13

Should that hose do the job? Also, thank you for looking into the bolt size for me. I appreciate it.

Yep, the hose linked above replaces the bottom AB Value hose perfectly. I ended up getting it directly from the retailer's website because they had faster shipping options and I needed to get this fixed ASAP. Here is the link to the same hose on their website: https://www.retromotioninnovations.com/collections/universal-parts/products/3-8universalmolded?variant=30325925838951

Nice I will have to order one then. Also I think I was wrong above, it wouldn't cause a vacuum leak because it's before the throttle body.
