[Diy_efi] Re: VW Surge / Expansion Tank Line Routing

[Karl Walter]

I don't know how small it can be.  It just has to be a volume large enough
to trap bubbles if the intake is uncovered.  I have no 3rd line, just an
in and an out, it fills up about half way at first, them the vapor
dissolves in the gas during use, and it fills all yhe way up.  You can see
this happen  in a carb car if it has a clear filter in line, it won't fill
up at first, but after a while it will be full.  I'm thinking about trying
a large filter as a surge tank, just to see how small it can be and still
work.

Let us know what you find.
