operate motor. If it still don’t move or slowly run, electric circuit or motor should be i fuel dispenser nspected. If not the rotor of pump maybe locked. Carefully check and cleanse oil strainer. 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 pressure 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 par fuel dispenser ts if necessary. If 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.

gration thing after all. Charles Cole Oakton, Virginia SIR �The ubiquitous paperboy fuel dispenser is no more and has been replaced, more often than not, by middle-aged recent arrivals. The effect of low-skilled immigration on wages, along with the declining value, in real terms, of the minimum wage, have made the decision of young people not to enter the workforce a no- brainer. Unfortunately their extra time is usually spent not on education but on the video games you write of in the same issue (“Playing a different game� October 28th). Warren Wilczewski New York SIR �It is correct to point out that raising America s minimum wage will not significantly decrease poverty because the poor population co fuel dispenser nsists of much more than simply minimum-wage workers (“A blunt instrument� October 28th). However, your solution of an earned-income tax credit (EITC) is also flawed. Just as a minimum-wage hike would not reach jobless individuals, an EITC would also not help the jobless because they have no income. Either of these initiatives could be part of a successful anti- poverty programme, but job creation and training provisions are also necessary. Isolated, non- comprehensive measures will not have much of an impact. Brian Levy Athens, Georgia Inhospitable for Martians SIR �I agree with your view, in relation to the Stern report on climate change, that governments should act on “the risk of something really catastrophic�(“Stern warning� November 4th). I propose investing in a space defence system to protect against alien invasion. Like the melting of Greenland s ice sheet, only a minority of scientists perceive this as a threat and the costs of such a defence are enormous, but if aliens were to invade it would also be a disaster.
