operate motor. If it still don’t move or slowly run, electric circuit or motor should be inspected. If not the rotor of pump maybe locked. Carefully check and cleanse oil str fuel dispenser ainer. If failure still exists after the above inspection, overflow valve should be checkup. In case that valve core jam, shut down incompletely or lose in valve seat the oil in high pres fuel dispenser sure area overflow into negative area, resulting in no delivery or inefficient discharge. Taking out valve core and spring so as to clean dirty, inspect valve seat at same time. If valve seat is loose re-fix it through oil-resistant glue or change a new pump. When find scrap of spring and graphite, washing overflow valve is must, changing broken parts if necessary. If fuel dispenser found rotor is stuck there would be several reasons related, such as spring broken, long vane, vane segment, lose bolts at top cover, etc. reassembling after overcome these reasons. Some manufacturers adopt new spring material evading broken. The lose match of rotor and axis of pump also result in no delivery or inefficient discharge. This situation will be overcome by changing rotor. After the above check and examine still find any rotor stuck or overflow valve abnormal, it is suggestive that vane abrasion is extensive, broken and spring damaged. Much abrasive vane can not successfully segment high and low pressure area, resulting no delivery or inefficient discharge as the areas exchange. The broken vane or spring not only cause flow trouble but also increase noise as whole. Furthermore, if they flow into other inner components may result in new failure. The solution to this is to change new vane or spring and clean out broken piece. It is suggestive that change all vanes if fuel dispenser have operated long time. Changing a new pump overcomes too large abrasion between frame and rotor. To check whether a leakage occurred in pine between fuel dispenser and tank, different diameter of pipe connection, bottom valve stuck or leakage. Abnormal noise and vibration The reason of

till viewed with suspicion in those countries that suffered most brutally under Japanese occupation—and Mr Koizumi seems unconcerned about riling them. Last year, both China a fuel dispenser nd South Korea called off summits with Mr Koizumi. Earlier this month, the Chinese Communist Party s official People s Daily compared him to someone who insists on eating “rat excrement� fuel dispenser This month, too, a Chinese state councillor and former foreign minister, Tang Jiaxuan, told a politician from Japan s ruling Liberal Democratic Party (LDP) that there was “no longer any expectation�of better relations between the two countries while Mr Koizumi was in power. Mr Koizumi is due to step down in September, to Chinese and Korean delight. Yet the Yasuk fuel dispenser uni issue is not likely to fade with his going. For a start, the Japan-as-victim school is no right-wing group on the fringes of Japanese politics though small, it is a core component of the LDP. Thus, every apology for wartime misdeeds that a Japanese leader offers is swiftly undermined by others in the ruling party. What is more, the two chief contenders to take over from Mr Koizumi as prime minister and head of the LDP, Shinzo Abe and Taro Aso, are both Yasukuni visitors. Mr Abe has been circumspect in his public comments since becoming chief cabinet secretary last autumn; but in the past he has usually visited Yasukuni on August 15th, the anniversary of Japan s surrender. The more outspoken Mr Aso, the new foreign minister, is, as far as the diplomats under him are concerned, a mounting liability. From time to time, Mr Aso extols the perceived benefits of past Japanese colonialism, notably in Korea and Taiwan. And late last month he said that since Japanese soldiers of the second world war had died in the service of the emperor, the emperor, too, should visit the Yasukuni shrine. As it happens, after the enshrinement of the war criminals in 1978, Emperor Hirohito stopped visiting Yasukuni, a stay-away continued by his son, Akihito. Indeed, as Jeffrey Kings
