Bypass hose

I need to replace the hose from the front of manifold to the heater core, my diverter valve has been removed, i currently have 2 hoses that are joined, I am fine with replacing as one single hose or replace with 2 separate, just not sure what hose to order from rock auto to replace from front of intake to where the diverter once was, what size, length

all help appreciated

You will need to go and buy (or not) the diverter valve. Then use cut to fit heater hose

Re: Bypass hose

many thanks for that, does anyone know of a hose that can be purchased that will run from firewall to front of TB, and part number if possible

or just a hose to run from front of TB to where the diverter was, as my current hose from front of TB connects to another hose where diverter was, if no part numbers what is the diameter of the hose from the front of TB?


Is it 5/8"?
