Thread: 50lb injectors

Has anyone used these injectors? I believe they are out of a ~2010 5.3, 6.0 flex fuel truck. From my understanding they flow 50lbs at 60psi.

Just looking for input before i buy, cant seam to find much information.


Part number: 12613412

They come on Flex Fuel 6.2 trucks from like 2009+ or so.

5.3 and 6.0 trucks use smaller injectors.

Factory fuel pressure is 58 psi on those trucks. If you can convert the data from a stock truck tune to work they should be fine to use. Most people just adjust the flow rate to their needs and tune from there on these 3800 computers.

So these will work? Then all i have to do is modify my injector table with hpt?

Maybe, never seen anyone try them before. Not sure if they have the same style injector connector though.

Overkill has 50lb injectors. I wonder if thats what these are? I read up on this along time ago but cant remember everything.

I'm pretty sure they have the uscar connector, so you'd need an adapter. They also look short, so you'd need spacers if that's the case.

Arent 04+ already uscar? And i found that they are about .75in shorter.

04+ are ev-6. Uscar is pretty much exclusive to pickups, if I'm recalling correctly from my research about a year ago.

I've been using them for years. I have the injector you'd need for them if you decide to purchase.

Sorry I meant injector data if you need it.

Were spacers needed?
