I’m really interested in the part number for those Mustang injectors so I can read up on the specs about them.
I bought a reconditioned set of 8 for $78 off of eBay. The stock green Bosch injector part number is 0280155787 vs. my reconditioned tan Bosch 0280155705 injectors…

Original D1 fuel injectors
Juke,
First off, let me be sure you know I own D1s. And I know this is the D2 forum. But there are general similarities regarding fuel injectors.

Two specifications are important 1) Size/shape 2)Rated flow (lbs/hr, #/hr, or commonly just lbs).

I notice the tan injectors in Juke's photos are missing the groove at the fuel rail end. That groove is for the metal securing clip, that might not be needed around town, but why risk it in the back woods. Both my old and new injectors are rated 19 lbs/hr. I am not sure what the model numbers are. Do you know the flow ratings?
