enerates 65”~85”W.C. vacuum pressure as operation, reclaiming vapor through reclaim pipe and nozzle, redundant vapor discharging out of exhaust pipe after vacuum pressure cap automatically open. Diagram 4-10: Built-in pump fuel dispenser with vapor recovery function Built-in pump fuel dispenser with vapor recovery function Showed in Diagram 4-10, this kind of fuel dispenser is mounted a vane pump that connected with the parallel pipes of oil delivery and vapor reclaim, in final connect into tank. At the refueling progress, motor drive vane pump operating and reclaim tank vapor through nozzle and coaxial hose. System maintenan fuel dispenser ce Nozzle and delivery pipe used in fuel dispenser with vapor recovery function are coaxial and double layers, simultaneously refueling and reclaiming. Paying much attention to nozzle body and delivery hose, in case of fuel dispenser waste, bad operation and crush by vehicle. If system alarm, carefully judge the type of alarm of monitor system whether vacuum degree or exhaust pipe pressure. Adjusting and testing vacuum pump and reclaim nozzle in for situation. Inspect air cap in the latter situation. If breakaway is pull down by accident, reinstall spare pin on upper of valve body. Don’t replace the coaxial and double layers valve with general one. Troubleshooting of vapor recovery equipment Oil spurt from nozzle’s reclaim spout before refueling. Solution methods: Prohibiting force refueling; Wait several seconds to take out nozzle from vehicle tank. Nozzle jump to stop in refueling process Solution methods: Maybe caused by second time operation, it is suggested not to force filing; Wait several seconds to take out nozzle from vehicle tank. Clean waste or deposited oil in air pipe of reclaiming nozzle or inspect O-ring seal. Chapter V Installation & debugging of fuel dispenser The design of fuel dispenser correlates to the correct o fuel dispenser peration. Fuel dispenser is designed to install outdoor with underground tank, not allowed to be in indoor so as to endure environmental

its alleged links to right-wing paramilitaries. The Democrats are likely to be more critical of Colombia s failure to prevent horrors such as killings of trade-unionists. According to Michael Shifter of the Inter-American Dialogue, a think-tank in Washington, DC, the Democrats are unlikely to halt the $600m or so of mainly military aid that Colombia gets each year since they will not want to be seen as soft on either drugs and terror ahead of the 2008 presidential campaign. Mr Shifter adds that the election has strengthened the State Department s role in dealing with Mr Chávez, reducing the scope for impromptu interventions fuel dispenser from hardliners elsewhere in the administration. Policy towards Cuba may change, especially if Fidel Castro, the country s communist president, were to die (see article). The Bush administration has hitherto fought o fuel dispenser ff efforts by a growing bipartisan group in Congress to pass legislation to soften the trade embargo against Cuba. That will become harder. In particular, a measure approved in 2004 which restricted family visits and remittances to the island may be repealed. It has gone down poorly in Miami, where Cuban-American political leaders have long been the main promoters of the embargo. The Democrats plan to hold hearings into a new report by the Government Accountability Office that criticised the poor management and lack of oversight of a programme to aid dissidents in Cuba. In one case, a Cuban exile group in Miami used taxpayers money to send cashmere sweaters, chocolates and computer games to supposed dissidents. The issue on which Latin Americans, and especially Mexicans, have highest hopes of change is immigration policy. Most Democrats opposed the plan to fence long stretches of the southern border approved by the outgoing Republican Congress. Like Mr Bush, they support a proposal, drafted in the Senate with fuel dispenser bipartisan support, which would combine tighter border security with increased legal migration and steps to regularise the status of undocumen
