Looking for the most efficient injector

[rfuntime]

My 6.5 diesel has 123,000 miles. Runs good, some say it is time to replace the injectors. Is the marine injector better, or just for more power. I don't pull with this truck, just trying to get the most mileage possible. Thanks! Paul

No "Marine" injectors are not suited for you. Boats have better cooling and can afford more fuel injected hence marine injectors (bigger nozzles). Trucks don't have the programing (or IP setting) for that much fuel unless fully modded.

Go with new or quality rebuilds of stock injectors. Use the search feature there are many posts with the same advice.

Yup good advice.
I set of quality bebuilt squirters will be perfect.
Depending on where you are your locality should have a shop that does diesel pump and injector work. Call them and see about exchanging yours for a fresh set.
