67 3x2 Fuel Leak

[Rich Garguilo #33425]

The threads in the end carb fuel bowl where the inlet fitting screws in are stripped.Does any one know of a repair or do I need a new carb or fuel bowl?Also are the fuel bowls still available? Thanks

Hi Rich:

Common situation unfortunately there is no "fix" other than to replace the bowls. They are readily available but probably won't match the existing color of your other carb components. These bowl threads when new will accept quite a bit of torque but deteriorate quickly with repeated tightening.

Good Luck.

I would urge you to correct the problem or stripped threads by replacement only. There are plenty of places you can get a new bowl assy. New and used if you desire. If you would like, call Pony Carburetors 315-662-3003 and maybe they can help or look in Hemmings Magazine or on the web for carb parts and number info.grr#33570

The real genesis of this problem is the effect which the scavengers in leaded fuel wreaked upon your carburetor during the many years that it drank a steady diet of high octane (and highly leaded) gasoline. The scavengers also wreak other havoc which manifest themselves in more subtle ways.

Anyway, for Rochester Q-Jet inlet fittings, which suffer from exactly the same problem, there is a Heli-Coil kit available which permanently repairs the problem (at least, the problem with the inlet fitting threads; not the other problems caused by leaded gasoline). This kit is very expensive, so folks don't usually buy one for repairing a single carb. Most of the carb rebuilders have them, though, and will perform this repair for a nominal cost.

However, Holley carbs use a different inlet fitting size, so the Q-Jet repair Heli-Coil kit won't work. But, perhaps they make another kit for Holley carbs. I would think that if such a kit is available, the major Holley rebuilders would know about it.

Hi Joe:

I have inquired about just such a fix as this is such a common situation. Our friend Jerry Luck says there is nothing of this nature available yet or in the works to his knowledge.

Re: 67 3x2 Fuel Leak

the sec bowls on holley 4 barrel carbs are a direct replacement, but make sure that you use the nitrofil float from your orignal float bowl as the brass floats have a longer lever arm and will hit the metering plate and cause all kinds of problems.
