Hi all,

After getting my car back to running condition I noticed that my clear fuel line now has a stream of small bubbles in it...

While some people say that small bubbles are normal it kind of makes me a little paranoid and in my readings to help you eliminate the air bubbles I read that somebody had put an electric fuel pump and that cured their air bubble situation.

That got me to thinking about other products that help remove air from diesel and some people even allege that it helps with performance...

Well I know some things like electric fans vs mechanical fans helps to increase fuel mileage would simply adding an electric fuel pump was it was none prior help to increase fuel economy by reducing the need for the pump to suck fuel as well as possibly eliminating all the air bubbles in the clear fuel line?

Has anybody here installed an electric fuel pump and notice any change in fuel mileage or performance?

Thanks in advance for any and all help
