Adding a gas tank return

[efi_student]

We had a Honda Trail 50 that we stuck a hose on and ran the exhaust into
the tank.  Let it run for about 5 minutes, then start work...

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?"
