Re: Noisy fuel pump (still!)

[jtrealty@xxxx]

It is very important when installing the fuel pump it is not turned as 
you will kink the pick-up hose, the oem or the replacement. The spring 
is good to keep a soft hose from collapsing under vacuum but it will 
also tend to keep you from linking the hose. There is no downside to 
installing a spring, it is a cheap solution. Just don't damage the 
hose when installing the spring. Trim the ends of the spring and bend 
so the ends of the spring are inside the coils. I don't think the 
problem is so much temperature related as it is more sensitive to fuel 
level being worse as the level drops. A real simple way to tell is to 
fill the tank. It also would tend to muffle the sounds as the pump 
would be inside the fuel. The replacement hoses are stiffer but can 
still be kinked if you aren't careful.
