[T3] EFI conversion

[Dave Hall]

You may also have some problem with the lack of a fuel 'sump'.  The Type 3
tank is rather shallow, and was modifired when FI came in with a collecting
cup in the tank that was kept filled by a venturi from the return pipe that
drove fuel up into the cup structure (see bottom of page:-
http://home.clara.net/hallvw/fuelsend.htm ). 

This may not be needed with an aftermarket system, but I suspect when the
contents get lower, the pump may draw in air.  The easiest way round it, and
one that would save welding in another pipe, is simply to replace the tank
with an FI one.  Never be tempted to put sealant into these tanks.

Alright,  thanks for the tips great stuff this will help for sure. 
 I know it will be a challenge to get that fuel line through the tunnel but
I know it can be done. If any one can think of a good way to do it please
chime in.
