Replacing fuel lines

[VW Scully]

Hi everyone;
I haven't been on here much this Summer; spending more time making Biodiesel and driving and showing my Rabbit!
It's been a load of fun and Summer is over too damn fast .
However, the Rabbit goes into hibernation in a few weeks ( :shock:  ) and there are some things I must fix on it over the upcoming Winter.
I need to do the headliner, replace the windshield and deal with some of the rust around the A pillar and windshield area as well as replace a fender.

Anyway, one of the more 'fiddly' things I must do is replace the rest of the fuel lines to be compatible with Biodiesel. I've done the ones in the engine compartment, but the one that comes up from the tank under the car and comes up by the fuel filter; does anyone know what size that one is?? It looks bigger than the other ones? :?:
Also, is the line metal from the tank up to the engine and then becomes rubber when it reaches the engine??
I don't have a hoist and haven't really bothered to look in great detail under there yet  :oops:
Any ideas how to go about doing this??
Thanks!

what's up VW Scully,

I don't really know if they make tank-to-filter biodiesel lines. I have an 81' diesel bunny myself and I wouldn't worry about the metal lines as biodiesel can't hurt them. As for the one going into the filter, I'm not sure. I just purchased a Viton kit from GreaseWorks.org for Rabbits but havn't seen it yet to make sure it has that particular hose....it should being that the original is that braided kind. If not I'm going to be pissed!
