injector washer

imcummin

to the dark side
I was going to put my injectors back in today but the cummins washers have 4 bumps on the inside of the hole. I guess these are to hold onto the tip so it doesn't fall off during install. But it appears as though they are too tight for my f1 tips. Do I need to get washers from F1 or should these factory washers work? It looks like they would scrape all the way up the tip...

Thanks for any help.
