FIC 650 NOT fit in rail, HELP

[93jdmlaser]

Please let me know if this FIC is for a dsm. I went to put it in my 90 rail and it did not fit. What is wrong?

It seems to look like the head ofhte injector is a little larger than mine but i have 850's.

Rub a little oil around the o-ring. Sometimes it's a really tight fit. You'll have to jiggle it around and everything until it fits. My FIC 950's had a hard time fitting, but they work fine now.

Is it possible that these inj. are for a different car? Any ideas on what car they are for if they are not dsm?
