Hello all,

I am a fellow Ford fan, however I do not own a Bronco, but a Mustang. My '68 runs fine, but my friend wants me to work on his car and fix the fuel problems. I tried rebuilding the carburetor, and it's still leaking. Here are the specs:

Block Code: C9DE-6015-B - Apparantly a 250 engine (which is why I came here, no 250 in a '68 mustang)
Intake Manifold/Head code: DODE-6090-A - According to my research this is a 170 code?! No way, is there?
Carburetor: Carter RBS (just rebuilt)

The problem is that I found that the carburetor spacer is cracked. I'm having a hell of a time finding a new one. Not offered in any of the books or anything. I'll post a picture shortly.

Hay SF..,
You didn't really say., is his a '68 'stang as well.?

Is it leaking "air" IN ---- OR Leaking "fuel" OUT ---- OR Leaking "fuel" into the manifold.?

"The problem is that I found that the carburetor spacer is cracked."
These cracks can usually be patched by opening the crack a tad with a Dremel tool (mini cutting wheel) & fill'n it with epoxy.

Believe someone on this board knows site with Ford eng. codes.
"D0" = 1970 & I believe that's a 250 head
"C9" = 1969 & I believe that's a 200 or 250 block.
----but don't quote me----

Yes, he has a '68 Mustang convertible. There is fuel pooling up all over the manifold, so it is leaking fuel out. Its actually intensely cracked though, as if someone tightend the bolts too much. The spacer doesn't appear to be sold in NPD's bronco manual or mustang manual.

Hmmm..., I don't have stock spacer/carb. BUT., to the best of my knowledge... all that runs thru the spacer is water, via the heater hose...and/or air fr. the PCV.
(A crack would leak water., or create a vac. leak & a lean condition.)

Fuel can only run external via a crack in the fuel bowl..., or a stuck needle & seat., or float level too high.
I assume it leaks mostly when eng. is runn'n & can be sopped/dried up with eng. off.

Well what appears to be happening is the fuel is leaking out through the gasket because the spacer isn't properly seating it.

Unless I'm missing something........my point is., the carb. could be detached fr. the spacer & held a small distance above & no liquid fuel should dribble or be visable anywhere....even with fuel pressure in the fuel inlet line.
Fuel coming from around the carbs gasket has to be an internal carb leak or improper settings.
All that (should) passes out the bottom of the carb is an air/fuel mist mixture...a "fog" if you will.
AND.., at the bottom of the carb., there's "suction"....not pressure.
