Im having difficulty buying this hose that connects the coolant tree to the bypass pipework. Its a 1992 gen2 engine and I have tried the following part numbers but they dont fit (dont come anywhere near to fitting) 16261-88361 and 16261-88380. From memory the coolant tree is 19mm ID and bypass pipework is 17mm ID, and the hose has a little kink in it.
 
Any ideas?
 
 

The heater hoses are listed in the parts diagrams, such as megazip.net

The only hose I know of as not available is heater hose number 5 which you use a HFHOE as is the correct sizing and had the kink needed - however don’t think that’s the one you are describing.

Most other hoses outside of HFH and HFHOE, best option is grab a kit from Stoney Racing and replace all - if one hose breaks the rest are soon to follow :)

I could quite easily be wrong here, but haven't you circled the water pump hose (16261-88361) in the first picture and then the second one is the heater hose (this one I'm not 100% sure on but I think its 16576-74010)

I found a suitable replacement in the hose bin at the local auto parts store. Not oem but been is service for years without issue.

Thanks Deevon I see where I have gone wrong thank you.
