Fuel Damper ?

[Mike (Perth, Western Australia)]

Hi chaps,

Have a high pressure fuel pump which feeds into a 'damper' then into a fuel
filter (all at the back of the car under the fuel tank) before going to
front of car for fuel rail and pressure regulator...

My questions are:-

a.	Are these fuel dampers really necessary or will a legnth of
	flexible compliant hose suffice ?

b.	What is likely to happen if you remove the damper ?

c.	Do they restrict the flow much ?
	If so is it nonlienar ?

Rgds

Mike
