any one ,this is pretty important that i find out.

different flow rate. The marine injectors are 42#. The regular truck injectors are 32 or 36# I believe. Just more flow from what I've been told. I've been looking around for bigger injectors myself.
The flow rate of injectors is somewhat dependent on the allowable psi that is governed by the FPR. For marine applications, the injector rating is determined with the standardized 43.5 fuel psi. So by the way of a lower fuel pressure rating at the injector nozzle, a marine injector is typically rated lower because they are based off a lower fuel psi. If you take the same injector and put it on one of our trucks, they will flow better when operated with the 58 - 60 psi the stock LS truck regulators put out. I am not sure, but the marine injectors may also have a different type of pintle style for their spray pattern...Single pintle style is one I know of, and another is a multiple pintle style with a good atomizing spray pattern. Some injectors spray different angles of degrees, different patterns of atomization, etc. So, typically, if you take a 30 lb.p/h truck injector and match it up against a marine injector ratred at 30 lb. p/h, then the marine injector will flow better because it was rated at a lower fuel pressure...the 30 lb marine injector would flow at about 34-35 lbs. because of the higher 58-60 fuel psi of the truck FPR vs. the 43.5 psi standard set for marine applications...
