Fuel Injectors

[mrttype]

I have a set of fuel injectors with a red stripe around them p/n 5208008 and another number on them-D1163AA. Does anyone know what lb. they are?

Scott,
I also have a set of new Bosch fuel injectors p/n 028-0150-845 that flow 64.5 lb. at 43.5 psi. What would be the flow rate at 45 psi like most fuel injectors are rated?

Actually, most injectors are rated at 3 BAR differential across the injector ... which is 43.511 psi. 45 is kind of a rare place to rate them.

Using one of the many injector flow calculators on the web ... such as

you end up with 65.6 lbs/hr with that injector (ignoring flow limitations, nozzle design, etc.)
