Carb coolant lines routing

    I pulled my carb off about 3 months ago and sent it to G and R to be rebuilt and tuned. Came back in the mail last week. Couldn't be happier with how it looks and assume it will operate as nice as it looks. Of course I pulled off the carb coolant lines to replace them at the time and tagged them all. Too much time passed, a couple of the labels fell off and now I am in need of some routing info.

    Would it be a good idea to start a thread on the routing of these lines for everyone to have for reference? We have so much on the forum about vacuum lines(think we have that covered by now)it would be nice to have some info on the carb coolant lines.

    By the way does any one have any pictures they can share or a schematic that shows or describes the proper routing?

    My 1993 f6a is on an engine stand, i just replaced al the vacuum and carburator coolant hozes
    I wil try to post pictures of the lines patway later this week.on my carb, there is 2 coolant circuits.
    One is to heat the carb body(in and out at the back of the carb),the other is to heat the chooke
    Element(in and out more on the side of the carb.)the coolant that feed these circuit come from the
    Wather pump outlet (near the thermostat hozing).all the other lines are return line going back
    At the inlet of the wather pum.(where the big prestoe pipe connect.(more toward the back of ingine)
    From the chooke circuit,the return passes through the intake manifold,comes out the intake and back to the inlet nipple.
    I wil try to post some pictures later this week.

    What size hose did you use to replace yours. I used the closest hose that my local parts store has but is is just a little smaller inside diameter(very hard to slip on if even possible), and the outside diameter is just a little bit bigger than the original(cannot get the stock clamps over it)causing me to use very small hose clamps which is very clumsy and not always enough room for it. I am going to check with boost controller.com to see if they have a better selection of heater hose size that is closer to the original size.

    Yes i had problems with the size of hozes. on the carb 1/4 inche hozes are perfect,but on the engine
    Block and intake i neded 5/16 in hozes.at the auto part store i found a T jonction that are made for
    3 differents hoze sizes.you just cut the plastic for the size you need.that is how i could match the
    Different size perfectly.

    Ok,here is pictures of coolant lines,you cane invert the inlet and outlet of thers circuits,
    The coolant wil stil do its job.

    Pou,

    Just wheeled my truck into the heated end of the shop today and started to pick through your pictures. My truck is really different than yours. Does yours have a turbo or AC or anything extra like that? I will take some pictures this week and put them on here of what I have. I do not have a nipple coming off of the thermostat housing however I have one coming out of the intake manifold under the carb just to the left of where the carb bolts on. Now from what I see you have four nipples total coming off of the engine, I only have three. Pretty sure will check again tomorrow.

    I do have AC, but we shoud have the same coolant circuit. #1, is the carb heating,#2 is the choke (wax element),
    #3 is the intake heating circuit.You need to find the nipple that provide the water pump pressure.the thermostat
    Hozing is right after the whater pump outlet. On my truck this is where the pressure comes from to feed
    The 3 circuits. All the coolant returns end up to the nipple at the wather pump inlet (on the side of the bloc)
    My truck is a Carry 1993 f6a .

    Started to put this back together today and changed most of the 1/4 lines to 5/16 coolant lines. Ended up snapping one of the nipples off of the coolant filter. Do you think this is really needed? Looks like a basic fuel filter to me would you agree. I took some nice photos of where my water supply comes out verses at the water pump, hopefully will upload those later this weekend.
