. Examine clearance and replace relevant components when necessary. 1.4. Measurement transducer block 1.5. No discharge due to Solenoid valve closed. First check electric wiring, then trouble on component itself (short circuit of winding or block in valve membrane, etc). 1.6. Pipeline and fuel dispenser bottom valve failure If continuously exhaust in vapor separator from beginning, disconnect filter cover and take out filter net; pour same kind of oil in it and given see oil level quickly drop, there is leakage occurred in pipeline and bottom valve. 1.7. No discharge caused by nozzle failure Jam in jointer or filter. Unlock strainer or jointer to remove dirt and waste. Nozzle always in auto-shut state, check auto fuel dispenser matic shut device, ma fuel dispenser inly inlet vent, spring. 1.8. Bottom valve be stuck in and pipeline is plugged. Exterior reasons for no delivery Oil level is so lower than bottom valve that pump can’t suck oil. Some valve(s) is closed in pipeline between tank and fuel dispensers. Air goes into valve(s). Single phase valve is rusted in bottom valve. Incorrect installation of flange causes leakage between inlet pipe and fuel dispenser. Inappropriate oil is refueled. Oil is easy to gasify; water in oil freeze; wax in oil plug pipe. Pipe design is unsuitable. Two fuel dispensers, for example, are connected in same pipeline without valve, or valve can’t shut completely; pipeline has many crooks or too thin. Slow flow rate as starting 3.1. Strainers, including cone-shaped filter net and nozzle filter net, are jammed. 3.2. Large amount of air flow into from broken parts or pipeline, causing much foam in oil indicator. 3.3. Large noise and vibration during operation Vacuum pressure is inadequate. Leakage occurs in overflow valve or pump gasket. Inner leakage in fuel dispenser increase as serious abrasion in pump vane or vane is stuck by waste. Vapor separator trouble Small floater of vapor separator is broken or fall down; insufficient pressure in high pressure chamber as exhausting valve can

upshot is that the central government s current spending is set to rise from 16.9% of GDP in 2003 to 19% this year, says Raul Velloso, a specialist in public finances. The mix of subsidy and stability, though, has done wonders for the poor. The poverty rate, as measured by the Getulio Var fuel dispenser gas Foundation, a business school, fell from 28% of the population in 2003 to 23% last year, which was comparable to the improvement brought about by the end of hyperinflation in the early 1990s. Lula s critics carp that the Family Fund merely alleviates poverty without providing an exit. That is to underestimate the value of reducing misery. The trouble is that although the total real income of Brazil s poorest hous fuel dispenser eholds rose 28% betwe fuel dispenser en 2004 and 2005, that of the middle class increased just 1.6%. Well-being in Lula s Brazil is unevenly spread in geographic terms, too. Cash transfers have animated the economy of the poor north-east, where retail and wholesale trade jumped 15.6% in the year to July. But this will tail off when the government ratchets back increases in handouts, as it must. In the southern state of Rio Grande do Sul, the economy shrank 5% last year because of drought, which hurt farming, and the strong real, which damaged industries such as shoe- and furniture-making. The economy of Rio de Janeiro, the second-largest city, has not grown since 1975. Enterprise there is thwarted by bureaucracy and high taxes. A third of the income in the metropolitan area comes from pensions. As Rio s stagnation suggests, the blame must be shared by earlier administrations and all levels of government. But Lula has done too little to spark higher growth. Investment, the best indicator of the economy s long-term health, has edged up from 18% of GDP in 2003 to 20%, not enough to sustain growth rates of more than 4%. Lula promises that investment will rise to 25% of GDP in his second term, but how? His government has done several useful things, such as passing a bankruptcy law. A long-delayed meas
