Hi Russ,

We have made the hose from scratch as we want them to be perfect. No branding on them at all.

For example, we used to have problems with the GRB and SH9 hoses. A lot of ebay items that customers brought in for the GRB and SH9 were always mixed up. The hoses will can be forced fitted into each model, but there will be issues as the actual hoses are slightly different between both models.

This was also the case for the GDB and BL5, where the angles of the cooling hoses are different but can be fitted regardless, but this actually impedes coolant flow.

Long story short, GR and SH radiator hoses look similar but are actually different and fitting the wrong hoses will reduce cooling efficiency. This is also the case of GD and BL.
We will be branding them once we have catalogued all the ones we are manufacturing.
