trying to determine whether this is a 24# injector, please read
 

Okay, I rebuilt my motor and had a bad 24# injector (bought used), so I go to the local Advance auto and asked for an injector for a 1993 cobra , which ofcourse came w/24#'ers. Well nowhere on the box or elsewhere does it say it is a 24# injector furthermore I ohmed it out and got 16.2, same as my 19# injectors, the other 24's ohm out at 14.2, so did I buy another 19# injector?

Unless it's color coded (blue = 24#, Orange = 19#) then it's not gonna be easy for you to check. Can you see a part # cast into the plastic part on the side?

It fits, doesn't look like any in the pic you attached tmoss, it's a sorensen brand and is a different part # than for a stock mustang so I guess it's a 24

man i had bought some injectors said to be 24's black with blue rings on top, turned out to be lucas/delphi 19's with no pintle cap design, I was so mad, and at least i figured out why my car wouldnt run right with the maf......

BTW the other 7 are blue FMS 24's for sure, I'm not as worried about that now as I am the overall performance of the motor.
Last sun. I went 9.00 at 77 with a 1.87 60 ft same as with my bolt-on stock motor :shaved heads 1.7rr's port match intake,(did it myself, hah!,looked awful), 3.73's pullies 65mm t.b., headers & h-pipe, flowmasters.then it was speed density so no mass air meter. It went 8.75@77 1.89 60ft.

I'm running 45# of fuel pressure and the plugs still don't look rich?
16* of timing with no problem, should I ease up on timing?
Someone said go to 38-39# fuel pressure but I'm afraid that's too lean as my plugs look whiter than tan after a hard run now at 45#?
HELP ME all this money in my motor and it's slower than b-4?
I CAN'T STANDS IT!!!
