Precision Injectors, lower insulator o-ring seal too big? Help!

[DSMDEMON93]

Hey guys, so I bought a set of FIC injector seals, to replace the old cracked ones on my Precision 1200s. All seals seem to fit just fine except the lower insulator that seals the head and injector. Here is a photo. Would this be okay to run? Since the fuel rail will be torqued down? The old insulators were smaller. Maybe OEM ones?

If it was me, I wouldnt chance having a leak so I would buy the proper ones. Fuel is something you dont want to mess around with and have a big leak. Could cause a fire and ruin the car.

That will not work. You could play ring-toss with that setup. Select your fuel injector type in the drop-down.
