Mike, a quick search of the forum using the words tire and bong using the "and" option will turn up plenty of reading on how-to along with photos. I found one post by Steve B., note the last sentence:

The bong has a schrader valve on the top to add air pressure. The brass valve is a bleeder. Bong is made out of 4" PVC (~48"), with glue cap on one end and threaded clean-out on the other. Holds about 2.5 gallons.
Always "seat" the tube by filling it with air, deflating, and re-inflating before adding fluid.
Process:
1) Hook tube to tire (valve stem removed).
2) Remove 4" threaded cap and add 2 gallons of washer fluid to bong.
3) Close cap and apply 3-5 psig ?(NEVER MORE THAN THAT) to bong to push washer fluid into tire/tube.
4) If tire over inflates, bleed pressure from brass valve and start over with 3-5 psig. Usually takes one bleed per gallon.
5) Repeat process until tire is full to point where fluid is just below valve stem at the 12 o'clock position.
IIRC, 8.50 tires take 5-6 gallons (35-48#), 10.50 take 7-8 gallons (50-65#), and 26x12 take 9-10 gallons (60-80#).
I ALWAYS ALWAYS ALWAYS use tubes with fluid (and prefer to use them in all my L&G tires).<!-/quote-!><hr size=0></blockquote>
