Surge Tank hose replacement

Go to solution Solved by klcdenver,

I am looking to replace the hoses to the surge tank and was wondering if 10mm silicone hose would be OK to use.  I have searched for info and can't find anything about the original specs on these hoses.  Any help would be greatly appreciated.

I just replaced mine on a 2007 diplomat. Should be the same size. It is a Gates Green Stripe 24920 are equivalent which I believe is a 1 1/4 ID. Make sure you use a wire spiral wound hose because you do not want it collapse.  It is stiff and hard to work with so make sure you order it long enough. I also suggest you order new heavy duty clamps.

Thank you again to klcdenver.  Just an update, I checked the 11/4" hose from bottom of surge tank and it is a spiral wound hose.  The 10mm small hoses from top of surge tank I will replace with Gates 3/8" silicone coolant hose.  Local truck shop guys told me the log trucks in this area use this product.  Also got the heavy duty clamps.
