Yep, my brother's customers used them for both diesel and gasoline.
As for the price, I thought maybe they'd just gone up because the company's own web site has higher prices than what my brother used to sell them for on the tool truck. However, like Mike said, I guess they don't want to undercut their dealers. I've found several non-related products to be the same way; I can buy them locally for less than I can order direct from the manufacturer.
