Because the manifolds has blanks plates bolted on them when not in use, and if you take off a blank you will want to know if any pressure has built up behind them from a leaking valve.
You also want to know if it is safe to disconnect a cargo hose from the shore terminal after you have closed the manifold valve.
Only if it has an engine or outboard motor fitted.
Sampans may be propelled by poles, oars or may be fitted with outboard motors.
Only if the mechanic is abusive and does not follow proper procedure
That depends where the regulator is fitted.
About 30-32 psi if recommended tires are fitted.
Temp sender on the 289 should be located at the front of the intake manifold. Source: www.AverageJoeResto.com
The fuel pressure regulator maintains a constant predetermined fuel pressure regardless of engine RPMs.
The EGR valves are normally circular in shape, they have an electrical connection on the top, normally fitted near to or on the inlet manifold.
Yes, when fitted on the proper size hose they will hold consistent pressure where a screw type of clamp will get loose as the hose ages and shrinks.Yes, when fitted on the proper size hose they will hold consistent pressure where a screw type of clamp will get loose as the hose ages and shrinks.
yes, most cars are not fitted with gaskets when manufactured. as you remove the exhaust manifold bolts the metal on both ends tend to warp and are not true to each other, therefore requiring a gasket to seal any potential leaks from the metal being distorted
Yes, and this is dispersed through static wicks on the landing gear which discharge static charges into the ground on landing. Fuel tankers are also fitted with ground-lines which are connected to the aircraft before re- fueling takes place.
Excessive pressure in the compressor, after the first stage (or how ever many stages there are). Excessive pressure could be caused by shut/ blocked discharge valve. There will also be a relief valve fitted to the intercooler, should one of the tubes burst. This would let air into the water side and suddenly increase the pressure in the intercooler, so a relief valve is fitted.
