Specifically i need the correct hose sizes to replace the hoses. My rack is only a few years old so i am trying to be prudent that I not destroy it by constantly running low on fluid and i currently can't afford the 60+ dollars to buy oem hoses so was hoping to just buy some appropriate cheap hoses.I tried using my digital calipers but the measurements didn't seem to line up to a meaningful size in fractional inches . What am I missing? Should I have been measuring in mm? Do they sell metric hoses? Any help is appreciated thanks!

53731-SV4-000 -outer diameter with calipers @ .89"
53732-SV4-000 -OD @ .69"
53733-SV4-000 -OD @ .69"
53734-SV4-A00 -didn't check this one.

 

Do you have a hose that is currently leaking?

 

The 2 short ones down by the cooler seem to be for lack of a better description, seeping through the hose. Wipe them clean and they'll be coated in oily grit within days. Still has those funny looking hose clamp that look like a tiny shackle with a screw.

The one from the reservoir to the cooler seems to seep from underneath the clamp. Haven't removed yet because want to minimize amount of p/s fluid il have to buy.

The one from pump to resevoir i don't believe is leaking but I mean if I'm draining the reservoir anyway might as well, am I right?

Il take pictures in a few minutes.

I didn't have drips but was aware it had a slow leak which had been an insignificant amount until recently so I just let it be. But I have refilled it now no more than 3 months ago and its at the low mark again. Previously refilling it was more a "top up" from halfway between min and max like once a year if that.
like I said car got a new oem honda rack from the dealer($$$ouch) in like 2014-2015. So id like to take care of it rather than chance accidentaly cooking a rack for not paying attention.
Only driven like 10k miles in last 2 years. Maybe a thousand in last 6 months
