8" Inner Tube (3.50 X 4.00 - 8)

The 8" Tube off the Wheelbarrow reads (3.50 X 4.00 - 8) Home Depot, Lowe's, Canadian Tire, Princess Auto all have the nearest Availabe size (4.80 X 4.00 - 8).. .. My concern is the Replacement may not expand properly inside the tire (???) Yes I could Patch the existing Tube but the leak is at the base of the stim ... How much difference in size ??

The way I read it is that your 3.5x4.0 -8 tube fits an 8 inch rim with a tire width of 3.5 to 4 inches. The tube you said is available locally is for widths between 4 and 4.8 inches. If your tire is close to 4 inches wide, it should work. Alternately, there are plenty of tubes for sale on the web that will be a closer fit. Also consider the style of stem. some are straight and some bend 90 degrees. Some are rubber and some are metal.
