Re: Noisy fuel pump (still!)

If you are going to worry about rust in the fuel system then you have 
more important parts to worry about besides a spring in a hose!!!! The 
allowable moisture content of gasoline is very low, it gets into fuel 
by being stored in leaky underground tanks, condensation, improper 
handling, and on a Delorean by bad seals around the fuel pump. If you 
have any doubts that there is water in your fuel, drain the fuel tank 
and look inside. Any appreciable quantities will be observable as a 
large bubble of water floating around in the bottom. Not only must you 
remove it but you must find out how it got in. After cleaning out the 
tank replace the fuel filter and on a full tank of gas add a can of 
drygas to break-up and disperse any remaining water. Water is VERY BAD 
for all of the metal parts of the fuel injection system. If you have 
water in the gas the car will sputter, hesitate and in general run 
crummy so if there is water in the fuel you can't help but notice it. 
The good news is that because of the abundance of fuel injected cars 
and their low tolerance for water the gas companies keep the moisture 
content very low. You can buy no-name gas as long as you use the same 
station often and don't have trouble. Even the discounters know if the 
tanks leak customers won't come back. In fact the EPA requires the 
stations to keep track of the levels to moniter for leakage and to 
also test for the presence of water regularly. Most stations now have 
fiberglass double wall tanks so they don't leak or rust.
