You can search on here, or use google. But basically you fill a pint sized paint can with mineral oil. Drill and tap the lid for a glow plug from a diesel truck, a male plug for an air compressor, and afix whatever line you want for the outlet. I used some old fuel line.
Hook the the glow plug to a battery charger at 2 amps or so. And set the air compressor to <10psi.
