They're just simple reinforced hoses and don't contain a return hose within them. The next time you fill up, have a look at the transparent section at the top joint - there's no black hose inside. The pumps are fitted with a venturi sensor in the handle and when it senses the nozzle is blocked by petrol, it cuts the flow.It also doesn't matter what time of day you fill up. The hoses are hardwall and don't expand, and the metering is by electronic encoder. A more important concern is whether the pumps are certified and occasionally checked for accuracy by an independent body such as the Weights and Measures Dept. A -1% variation is a lot of money over time. That's why we tend to pick a brand with a good corporate integrity reputation and good control over their dealer network isn't it? :wink:</blockquote>
