Pretty random, wondering if anyone happens to know the size of the send and return lines (inside diameter) from the power steering reservoir. I need to run one custom line from the reservoir to clear a Nismo intake.

You can see them both coming off the bottom of the reservoir at the top of the photo. Stuck at work and will be up at dawn to make the necessary modifications and get everything installed to my satisfaction.

Any help greatly appreciated!

 

Subscribed. I need this info for when I do the ps flush later this summer. Actually both OD/ID would be nice.

 

3/8" is the most common, most all cars use it. To be safe though, you can take your OEM hose to any auto parts store and they'll cut one for ya.

 

Ok so I didn't want to pull the hoses off and measure the inside diameter (til tomorrow) but there are two different sizes. The larger size runs from the reservoir to the actual pump and the smaller size is the one that interferes with the Nismo lower pipe.

I slid the larger hose down ever so slightly and measured the OD of the nipple at 15mm. The smaller one I didn't measure because I didn't realize it was a smaller size. The 3/8" hose is the closest (9.5mm) so I'm assuming it's a 10mm hose.

I'm not sure which way flow goes but I think it exits the reservoir via the larger, shorter hose which goes directly to the pump and comes up through the smaller. That'd be ideal as I could swap hoses in without worrying about introducing air into the system.

 

From the FSM, #9 and #10. If I'm reading the pic correctly, fluid flows out from #9 and comes back in through #10.

Introduction of air is not a big issues. It's easy enough to bleed by just turning the wheel lock to lock slowly a few times.

 

Ah good to know! #9 is the larger hose, 10, the smaller (in diameter).

Much appreciated.

 

Would you believe this damn part is like $150+!!! For the reservoir!

 

Wowza. I'd go aftermarket. There has to be some cool as **** billet unit out there for half that cost.

Also, I switched out the hose today and a 9mm hose would be optimal. The 5/8" (9.5mm) fit fine but it was super snug.
