hey guys,
I have a 69 coupe with a 302. I have an edelbrock intake and a holley 4 barrel on it. My problem is the manifold fitting behind the carb literally buts up against the carb, I put it on the intake where its stock location was, (right behind the carb) but it was a stock 2 barrel car so it was never in the way. Can I relocate this to another place? or do I even need it at all? It has a hose going to the triple nipple vacuum fitting by the thermostat and the other hose going to the vacuum canister behind the passenger side fender. Thank you guys in advance
-Randy

i could use a little more info.. perhaps some images..

use photobucket to upload your images and then paste links here..

there are A bunch of different vacuum fittings available from different sources..

somewhere in my computers i have a page.. with a bunch of different vacuum fittings..  i know i have a gm version but i also have a ford version..  i will look around for it..  i only have about 70,000 images to page thru .. at last count..



i am taking its a 4160 holley carb without a secondary metering block.

.also the intake manifold model number.. if other than the 2121 performer..  as they also currently offer a torquer II for the 289/302 windsors

1000X1000


if you only need a quarter inch to get your carb down.. there are 1/4" and 5/16 thick gaskets you can use to move the carb up slightly for clearance.  you might look at a felpro 60327 carb mounting gasket

Yes it is a 2121 performer intake. And I uploaded two photos one without the carb and one with the carb. I used a thicker carb gasket and it gave it some room. But on hot days the heat of the carb will sometimes touch one of the vacuum nipples and actually melt a hole in it and cause a vacuum leak. If I move the attachment to the other opening  further back it is directly in the way of the throttle cable. I would like to get rid of the darn thing all together if I don't need it.

thats easy...

it looks like its 3/8 NPT  (national pipe thread tapered)

your thread size might be 1/4 NPT.. i cannot tell by the image..


a 90 degree street ell...  

this is not the proper size in the image but it is the proper shape..

Adf4e32c Af30 49B7 9213 62Dbd8c3b447 300


Watts3/8 in. Brass 90-Degree MPT x FPT Elbow
Model # LF A782
Internet # 202254934
Store SKU # 732389
many stores sell the watts brand brass fittings.. there is a big board with them hanging in display bags..

if you don't want to go a full 90 degrees.. there are sometimes.. 45 degree street ells available..  or you can go with two 90s.. so you can place them at a off angle. or just step it back an inch by installing the first one aiming toward the rear and the second one straight up..   you are just moving air.. and not even that much so going thru a pair of 90s is not going to be a restriction..


you could also change the location from the #4 intake passage to the #8 passage as i can see a pipe plug in that intake passage also in your picture..  or is that right in the way of the throttle linkage as i think you described..

Those clear plastic float level sight plugs were neat until I tried to remove them after being there for a while. The clear outside twisted right off and the threads stayed in place. Had to remove bowls and floats and drill/pick out the plastic threaded half. The old stock brass ones went back in. bad idea.

Honestly didn't think of a 90... I guess keep it simple stupid applied to me. I was looking so into relocation I never thought of that lol. Thank you. Also thanks about the clear sight plugs, I had another person tell me a similar story. I'll be changing back to the brass plugs once I find them. Thanks for the help and advice

Or just remove the plug on the other side, and install the fitting in its place, and plug that hole..

I tried that already. It gets directly in the way of the throttle cable. I used a 90 and it worked great, mostly hidden by the air cleaner too.
