How can you tell your fuel injector size? Is it marked on the injector itself? Just curious b/c when I switch intakes and put on my super charger, I may have to have bigger injectors and the 350 I bought may already have fairly big injectors. Anyway, thanks.

i know thesvo injectors i have in my 383 are marked 30lb on the top, right underneath the connector... and my accel24lbers are also marked in that same spot, but my stock injectors had no markings.... hope that helps. by the way, what color are the injectors? yellow is normaly accel, red if ford SVO and light blue or black is commonly GM

Look up the numbers on them. You can probably cross reference them online somewhere, depending on the brand. If you post a pic or describe them maybe someone can identify them.

Ford injectors are actually many colors. They have a gold/yellow which is 19, a blue which is 24, red which is 30, and green which is 42. They have others, those are just the ones I remember. Like suggested above, look for any numbers nad see if you can cross reference them some where.
