Maybe I can reveal a secret for reducing the incidence of fear related heart
troubles among Lotus 7 (& copies) owners who are considering installing EFI.

If you have a MIG welder, then welding in the tank is no problem.  Run the line
from the shield gas (Argon?  CO2 mix?  Whatever you use..) into the tank and use
this to flush out the air before beginning welding.  Now the only thing to worry
about is "Did I let that run long enough?"
