That kit comes with the nozzle hose to fill up your car from it - I think its gravity fed rather than pump.

Apparantly the only issue with using biodiesel is if you have an old car that uses rubber fuel hoses - these need to be replaced.

From what I've read, the issues with biodiesel causing problems to engines is where its not been made properly.

As per gingeRS, you are supposed to change your fuel filter shortly after using biodiesel because of its cleaning properties.
