I am replacing all the heater hoses and the control valve. Toyota has this weirdly shaped brass tube that acts as a t-fitting and 3 piece assembly of two rubber hoses and a U-shaped metal tube connecting to the control valve. Could I replaced the long metal tube (marked blue on the pictures) with a stainless steel or aluminum T-Connector and the 3-piece assembly (marked red on the pictures) with a longer 5/8 heater hose ? I believe this is the set-up in 100 series. Has anyone done this?
