FMS 36lb injectors

I bought some used 36 lb injectors but the clip that holds the injector to the fuel rail won't clip in the second groove it will clip in the first groove but I don't know if it is setting far enough down in the fuel rail. Do I need differnt clips or what? Also is there any way to make sure they are 36 and not 30lb. The part # is F1SE-E5A the other side is 290 280 150 945. Thanks

im pretty sure those are 30's ..they have the same part number of some REDTOPS that I got and mine are suppose to be 30's

I looked up the part number and they are 30lb now will they work with the stock clips that hold them to the fuel rail?

i put the 30 lbs. on my lt1, and used the groove that the clip fit into. I modified the other groove to accept the clip, but the injectors sat too high in the rail to seal in the intake. So yes, use the groove the clips fit into.

Thanks thats what I was needing to know.
