Injector springs
Are stock injectors single spring or double?

Just wondering if they spray in one shot (single) or multiple (double)

They spray in one shot as far as I know. Basically, the pump overcomes the injector spring that holds it closed, then as long as the pressure is above the injector pop pressure, fuel flows out the tip.

They are all single springs, shims underneath the spring to set the pressure. This isn't a common rail or a HEUI injector so one shot is all you're going to get.

Yup, squirt straight into a bowl in the top of the piston.
