Getting fuel without tank to the engine

[Jozi]

I need to get an engine running but I've removed the tank to get it cleaned up a bit (and pulled the mounts from the shell). Is there and easy/quick way to get everything hooked up rather than refit the whole tank and everything attached to it only to have to pull it all again when I know the engine runs?

Use another tank on the floor next to the car with some long bits of fuel hose

Does the over flow catch thing need plumbing in or can I just use the feed and return?
