Good evening,
I am looking at doing the whole injectors / coils / spark plugs job on my 2010 Rapide (78,xxx miles), and I am looking at sourcing new injectors.
I can see the AM part number for the injector is 5R139F593AB which links to a Ford 5R13-AB which links to a Deka EV6 injector.
However, there are several versions (46 lb/hr, 60 lb/hr, 80 lb/hr) of the Deka part.
Does anybody know which version is proper for a 2010 Rapide?
Thanks in advance for your help!

 

Another question: is it possible to remove and replace the injectors with the injector rails still hooked up to the fuel line?
Thanks!

 

Probably not the definitive answer you're looking for, but based on the tuning I've done, and just a matter of physics, a 6L naturally aspirated ICE is going to be in the 46lb range (43 - 46). I've refit 60 and especially 80lb injectors on 6L platforms only when I've converted them to FI.

EDIT: I should have also said, you cannot guess here either, BC if the EMS is programmed for 46lb injectors and you install 60 lb, the injector data will be off and w/o access to the data tables, you won't be able to modify those. And with injector data, really have to know what you're doing.

 

Why not just service the injectors instead of replacing?

 

I've used a place in NY Injector Repair LLC. They test, clean and install new filters and O-rings for a very reasonable cost. And provide percentage flow before and after their service. $20-$25 per. I believe. Injectors were within 5% dirty and it wasn't much after cleaning 3%?
70k miles on them. If you lookup the AM number several places quote 22# Injectors.
I would definitely not go much larger as BWings says. Mustang GT of the era used #24 Injectors the V6 used #22 ones.
I would be hesitant to buy Injectors only to create issues if you don't have a fueling problem.

 

Yes, I looked into this option too, thanks to the link I found on this forum.
Reading all the answers, I guess that's the way I am gonna go.
Thanks!

 

There must be some fairly local places that rebuild injectors to you.

 

There is several local Injector service companies. But my friend insisted on sending them to NY. Due to the review from Aston1936. It can be a DIY if you have the simple components.

 

Yes, it's possible and I left mine connected to the fuel line when I did my coils a couple years ago. If I had the correct disconnect tool it would've been an easier job if I could have removed them. You can never really get the rails completely out of the way.

 

Good luck with the job! As others have suggested, I'd get the injectors serviced and calibrated unless you can get your hands on some OEM ones at a good price!

You can definitely leave the fuel rail connected when doing the coils, but I found that it got in the way, and it only took 2-3 minutes to remove them with the right tool (sent you some info yesterday), and it makes it a lot easier to move in the cramped area.

 

Thanks for all the info!
How about removing the actual injectors from the rails? Do I need to block the fuel line at the rails, or can I leave it hooked and "simply" remove the injectors from the rail?
