Identifying Injectors

[Powerwagon64]

Hello.
Thanks for your interest in my thread.
I bought a set of injectors described as new in the box F1 Mach 7's.
When I received them there was no paperwork or receipt for them in the package.
Is there a way to identify Mach injectors and more specifically F7's.
I have asked the seller many times for the paperwork and receipt but have nothing yet. Been a couple months now.
I was thinking I may be able to spare the cost of flow and pop pressure testing these, maybe not.
Maybe F1 could tell me, didn't want to bother them as I am not a direct customer of theirs??
Any ideas?
Thanks.

Send them to F1, they would be able to give you a definite answer whether or not they are thier injectors.

Send themto F1, but don't be in a rush to get them back from what I've seen on here.

Return to F1

Thanks guys.
I will do that.
Was hoping to avoid the costs.
