[DML] Re: Coil in Fuel Line to Prevent Collapse?

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

I have had a spring in my pick-up hose for years and I inspect the
internals once a year. Here in New Jersey we are up to 10% Ethanol and
I see no ill effects. I think the "trick" here is that you must very
properly install all of the parts and they must all be in good
condition. If you put any twist into the pick-up hose or reassemble
any of the baffles incorrectly you WILL have problems. Most of the
cars I do go inside the tank on I usually find something done wrong.
Among the problems are:

Excessive fuel pump noise
Gasoline fumes
Engine problems especially when the tank is below 1/2 full
Fuel leaks
Water and dirt
Corrosion from water entry into the upper pump boot.

I do not have any problems filling my fuel tank and I get no fumes
even when full and "topped" off.

IMHO a "tuna can" (a METAL can) is not a good idea. If any water
should get into the tank it goes right to the bottom, exactly where
that tuna can IS! That can will rust and fill the fuel system with
crud. About the worst thing you can do to a fuel injected system is
allow dirt (crud) to get in. Water is a close second because it
promotes the formation of crud.
