Universal Portable EFI Tank

[Citroënbender]

How good would something like the grey unit, be?  All it needs is an adjustable regulator (2.5-4 Bar) with gauge, inline filter and a bunch of connector fittings for the pump/sender.

Perfect for repairs where the tank or pump has to come out, yet keeping a car mobile is really helpful.
