Small Coolant Line From Intake To Block

Recommended Posts





This is a two barrel hogged out intake manifold. The main coolant lines will be plumbed through it. I am having difficulty sourcing the proper small 7.3mm ID diameter intake coolant bleed line that connects to the block from the intake manifold. Could someone point me in the right direction via realoem? Alternately could this small line be plugged both at the block and the intake? Thanks!

Not quite sure since I replaced my intake with a cannon, but it may be for a water heated choke.  If that's the case then you need fuel line hose that is listed in realoem in carb section as 16121180409.  If you don't have the water choke then block off both ports or run a hose between between both.

I don't have a water-controlled choke Weber carb (but, if memory serves, there was one on my car at one time - I've been driving it for 32 years, so I don't always remember everything. I currently run a 38/38 with elec. choke) but I do have that hose from the brass-colored outlet in your photo down to the block (under the #4 exhaust port).


I would think Blunt could help you out on supplying it:  blunttech.com

If you use bolts to block off the ports (after removing the nipples) be sure and coat the threads with an anti-seize paste (dissimilar metals and water don't play nicely together) and use a copper or aluminum compression washer to seal.  Did that on my '73 around 1981 when I went to a manual choke Weber and deleted those two little hoses...

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
