temporary tune-up tank

[moto pierre]

Trying to get my damned tach to work, and other tuning work means running the engine with the tank off. On other bikes (with carbs) my shop tank, a Coleman fuel can with a barb fitting soldered into the side, works fine, but on the Guzzi (and other fuel injected bikes I suspect) there has to be back pressure in the fuel line for the injectors to work, hence the regulator on the right side of the tank. I put a T fitting in the fuel line from my Coleman can, and connected another line from the T to the tube that feeds the regulator from the right side injector. Pinching this second line allowed the engine to run, but occupied one hand and made me nervous about spraying gas all over the garage. I suppose an adjustable clamp would serve as a "regulator" but haven't tried it yet.

 

Does anyone have a better idea for a tune-up tank that would work on the injected Guzzi motors?
