Be careful, some injectors are called Peak and Hold. Basicly, the injector
takes a higher current to open, then needs a lower current to keep it open.
If you supply to much current to this type of injector you will overheat it
and burn it out.

Just a followup..

Found this while searching.

Interesting, and I have a regulator and pump.
Problem is the connector, possibly just hose
and a pipe clamp would work to feed the
injector.
