Re: Is a worn fuel pump causing my engine to die??

[jtrealty@xxxx]

Although the fuel pump can "wear out" the trouble is usually a suction 
leak that allows air into the pump which causes all kinds of running 
quality problems and will eventually lead to premature failure of the 
fuel pump. The fuel pump is lubricated and cooled by the fuel so if it 
is pulling in air you can guess what happens. Before replacing the 
pump carefully inspect the pick-up hose and make sure it and all of 
the baffles are correctly installed. Also when installing the fuel 
pump use extreme care to not kink the hose. If the hose seems soft 
replace it because the fuel pump can collapse the hose with the 
suction it can create. Alternatively you can install a spring inside 
the hose to prevent kinking and collapsing. If these tips don't help 
and the pump is still noisy it is probably shot and will soon quit 
completely so change it but keep it as an emergency spare. Cars with 
this problem always seem to do better on a full tank of gas, it covers 
the hose and cools the pump.
