efi fuel tank baffle

[eric schumacher]

I personally can certify that it is a problem when converting from carbs of
FI. I can also second the reply that VW (my only experience) sumps in the
tank are very complex. They are usually plastic affairs that include a big
SS strainer and later ones include a pump so they don't have to gravity feed
the main pump.  In both my conversions I added a small external header tank.
In one case I made it myself out of a Bernz propane cylinder that was
gravity fed from the main tank.  I could never get it to work right. Ended
up using a small plastic tank designed by VW and used on all 16V Sciroccos.

For what it is worth I weld SS all the time with my wire welder and usually
use plain old steel wire. Obviously the joint can rust but that is not much
of a prob here in LA. I weld on gas tanks by flushing them out with hot
soapy water,  drying in the sun and blowing air inside from a backwards
vacuum cleaner while drilling/welding.
Lotsa Luck Eric
