    Default Small Block Chevy in a JEEP CJ7 - EARL's Heater Hose Ideas?

    Hi. Love your products and technical support!

    I'm looking to install your products on my cooling & heater hoses on my JEEP CJ7. The heater core is 1/2" & 5/8" hose connections and the SB Chevy is 5/8" & 3/4". I found some adapters to up-size the heater core on the JEEP to 5/8" & 3/4" to interface with the SB Chevy. Is there a "heater hose" kit? The fitting in my Edelbrock intake manifold is a beat up brass fitting (looks pretty shabby). I'm looking to replace that also. I'm also replacing the water pump with a new high flow pump and therefore have the option to put a NEW fitting into it. Any thoughts? So can you hook me up with some part numbers for fittings for a simple install of Earl's hose in black with the neat looking fittings? For the radiator input & output I need to get some flange OD/IDs before I ask. Jim

    Earl's doesn't have a "heater hose kit" per se, but they certainly have hose that's suitable for fuel, oil & coolant. Which hose do you want to use?
    For 1/2" & larger diameter "push-on" hose:
    I like Earl's Super Stock hose with the easy Super Stock hose end fittings.

    For 5/16" & 3/8" EFI "push-on" fuel hose:
    I like Earl's Vapor Guard hose with the easy Vapor Guard hose end fittings.

    For stainless steel braided hose, -6AN & smaller:
    I like Earl's Speed-Flex hose (PTFE lined) with Speed-Seal hose end fittings.
    Olive type (LINK/LINK) screw-on collar (reusable) fittings are the only style hose ends I use.

    For stainless steel braided hose, -8AN & larger:
    I like Earl's UltraPro hose with UltraPro hose end fittings.
    Olive type (LINK/LINK) screw-on collar (reusable) fittings are the only style hose ends I use.

    The fitting in my Edelbrock intake manifold is a beat up brass fitting (looks pretty shabby). I'm looking to replace that also.
    What are the specifications (thread/barb size) of this fitting?

    So can you hook me up with some part numbers for fittings for a simple install of Earls hose in black with the neat looking fittings?
    That depends on which type of hose and hose end fittings do you want to use.
