I should start a retainer fee of sorts soon.

Or maybe a service fee for every question answered?

So does this mean that for SGI installs, a hole must be drilled near the injector for the LPG injector? And that it might require pulling out the engine.
Yup, they will drill a hole into the intake manifold for every injector to be installed. Usually the worst case would be to remove the intake manifold from the engine, not pulling out of the entire engine.
