anyone using the pink top injectors from 50 motorsport (22#)?
I need a set of replacements and I don't want to have to get a chip to run them like the SVO 24#. I am wondering if anyone has tried these and if there were any problems? Here is a picture of what they look like:

Thanks for any help!

I thought the pink ones were rated at 19lbs. I got the blue ones and they are 24lb. I dont think Ford Motorsport or SVO makes a 22lb injector.I know Ford rates there flow differently than GM so the pinks rated at 19lb from Ford might flow 22lb.as rated by GM.

Ive got them...just put them in about two days ago....MUCH better than the SLP 25lb injectors(even with a PROM burn). My car runs so much better with them...idles like its brand new. The install fine and havent had ANY problems yet. Good luck.....

KYL98, that is exactly what I wanted to hear. I had already purchased them off eBay and was hoping for the best.
Did you have to change the o-rings or did you just put them in as is? Which groove does that lock go into?
Thanks again!

I too have used these for the past year and they worked flawlessly. I did nothing to the ECM. I am taking them out though now and am upgrading to SVO 30# because I am switching, heads, cam and intakes now. You'll be more than happy with them. Also, you don't have to change anything concerning the o-rings. The ones it comes with are correct.

I used the original GM o-rings.....they seemed to look and feel thicker in size compared to the blue orings that come with them. BUT, the blue ones should be fine.....The retainer clip goes into the top groove... the injectors wont go down into the bosses in the manifold if you try to use the 2nd groove. If you need any help installing them...just email me or send me a PM....Ill be glad to walk ya through it....good luck.

just posting a followup on those injectors. They fit perfectly using the o-rings that came with them and the swap wasn't that difficult. It's amazing how a car can feel like new with new injectors in it. My rough idle when warm is gone and the car runs stronger than ever. I'm hoping the gas mileage will go up as well.
Thanks everyone for the help!
