Carburetor overflow tubes
« on: September 23, 2017, 05:13:08 pm »
If you have overflow tubes installed on your fuel bowls, will you still be able to drain the fuel bowls? Can overflow tubes be installed, do it your self? Can you buy fuel bowls that have overflow tubes already installed?

   You can install float bowl tubes yourself but if you screw them up you buy $$$ NEW float bowls.  >:( >:(

   Steve probably has some on hand (float bowls) or you can send you float bowls to SiSF  and he will install overflow tubes. He has probably done about 500 sets or more.

Procedure wise, installing your own tubes is straightforward - make a hole in the bowl bottom, cut tube of proper diameter to correct length and insert.

Technically, there is a bit more to it.

1) Length is critical - better know what you are doing

2) Fit is critical.  You cannot use adhesive.  It has to be a pressure retention fit, meaning the hole must be a fairly exact diameter - too tight for you to simply press in by hand, so you must expand the hole while contracting the tube itself.  Hot and cold works for this.  The hot bowls cool off and shrink while the cold tubes warm up and expand.

As far as diameters and lengths?  I don't know.  I didn't bother to measure mine the one time I had access to them, but surely someone here can tell you.

    Rick is right! That is why I had SiSF do my overflow tubes. A man has ta to know his limitations. And I have been around long enough to know that I can "SCREW" up a free lunch!! >:( 

  " Can I clean carbs? " I have done it but after I sent them to SiSF I found out what a really "MEKANIC" can make my carbs better than NEW!!!!  Thanks,Steve! :)
