Fuel valve is not included, selling ONLY the knob=NOT the knurled part... Here is a solid Black Dakaware plastic knob for the "IN THE TOP OF THE TANK" Gas(fuel) Valve Flow Rod on HARLEY DAVIDSON --KNUCKLEHEADS, PANHEADS, UL's and 45 FLATHEADS-(both servicar and solo models,). This knob will only fit the "Original" Harley gas/fuel rods, it has the same size(diameter) stud and very fine threads that fit the original Harley fuel rod.,it will not fit almost all of the remanufactured gas/fuel rods because most of those have a larger diameter hole with course thread..but with a little ingenuity things can be done to the remanufactured rod to make it fit...  This knob is solid, smooth on the lower area and is textured on the recessed top, knob also has a shine, it might have some scratches and or scuffs but has no cracks.. This extension knob is a really great aid in opening the gas/fuel valve on your vintage ride, makes it MUCH EASIER TO LIFT THE GAS/FUEL FLOW ROD. . it also Adds a little something to the overall look of your bike.  This knob  (not counting the stud) measures 3/4 inch tall and 1 inch wide.  the permanently attached steel stud protrudes at least 5/16 of an inch out of the bottom. Most of the knobs have a black steel stud instead of the silver one in pics.   IT'S A VERY NICE  LITTLE ADDITION FOR YOUR VINTAGE RIDE ,, email with any questions,,I SHIP THIS KNOB First Class IN A BUBBLE ENVELOPE in the LOWER 48 States for $7.05 and comes with tracking,,      THE COST TO SHIP OUTSIDE OF LOWER 48 STATES IS $24.75 tracking is always included .   I have lots of items to list so keep a watch on my auctions. i combine shipping when it is possible to save the buyer money.   Please take the time to check out my other items!
